Selecting the Proper Ball Weight


Adults:
The weight of the ball should be roughly ten percent of your body weight. Another good rule to go by is to choose a ball that is one to two pounds heavier than the house ball you are bowling with. The reason being is that the grip on the house ball is incorrect and a custom fit ball will feel much lighter because it will be easier to hold on to.

Kids: We recommend a weight equal to their age. Please note 6 & 8 lb bowling balls are designed for kids only not adults. Some manuacturers will not warranty 6 & 8 lb balls that are drilled for adults.

What is the Pin Placement of a bowling ball?


The pin placement of a bowling ball is the distance between the center of the core and the CG. How far the pin is from the CG will help to dictate the balls reaction on the lane.
 
The shorter pins like (0 - 2") will roll up earlier on the lane, and will have a smoother arcing motion to the pocket.
 
The longer pins like (4"+) will go much farther down thelane before starting to hook toward the pocket. The longer pins will also have a more dramatic motion toward the pins (possibly like a hockey stick shape or a skid/flip type of reaction).
 
The (2 - 4") pins are the most versatile to lay out for your ball driller allowing them to manipulate the ball path and have it roll up earlier or later depending on how they lay the ball out.
 
Why is this important?
You want to have the bowling balls natural intended reaction to match up with your drilling pattern you select for the bowling ball. If you get a short pin but want the ball to go long the ball will want to roll up early, even if you drill the ball to go long. This will cause you to have to loft the ball or push through it harder to try to get the desired ball reaction. If you would have selected the correct pin distance and applied a complementary drilling to the ball, you can throw the ball with much less effort, and let the ball do the work for you. This allows you to relax and be smooth, improving your release and scores.

What is the Top Weight of a bowling ball?


Top weight is the amount of weight difference from the top of the bowling ball (CG) and the bottom of the ball (opposite the cg).

In general their will always be more weight to the top of the ball (CG). This is due to the fact that when you drill finger holes into the ball you are extracting weight from the ball (generally 2 ounces or more depending the hole sizes and the density of the core) and it was initially designed to keep the ball balanced after it was drilled. 

Balls with lower initial top weight were generally more stable after drilled than those with higher top weights due to the fact that their was so much weight left over after drilling. This created imbalance and often time added length and backend reaction for early three piece (Pancake weight block) bowling balls.

Top weight by today's standards is not nearly as important because a majority of the weight mass of most bowling balls is closer to the center of the ball than the shell and top weight has less of an effect because ball motion is more about the placement of the weight block itself and not the static weight mass. Top weight these days usually dictates hole size for those off label drillings.


What does this mean in selecting the correct top weight?

2.5 or less - Is for standard drilling techniques. It is also used for advanced drillings where moving the cg further off center of span creates a stronger drilling. You may not needing a weight hole with this type of drilling but depending on how far the cg is moved you may need a weight hole.

2.5 to 3.5 - Is great for normal layouts, a weight hole is not typical for this top weight. Stronger drillings may require a weight hole.

3.5 or more - This top weight is good if you want the ball to push more (go farther down the lane) while adding backend motion, but only if the ball driller knows and incorporates this into the drilling.

It can also be used for placing a big weight hole in a ball because it adds static weight to the drilling. This means you can use a stronger drilling than normal but make it legal by adding a weight hole to remove excess top weight (you can only have 1 oz of top weight remaining after drilling).

***NOTE: These are just basic descriptions to what top weight can do. There are many more scenarios for each top weight and what is capable with each different top weight range. Please discuss with your ball driller how they plan to drill you ball to get a better idea if they plan to use a weight hole or not to achieve the ball reaction you desire. There is no way to guarantee a ball will not need a weight hole depending on the top weight selected, the ball layout will determine that.

Shoe Size Charts

900 Global, Brunswick, Dexter and Storm shoes run true to size.

 

Right Handed Shoes: Made for bowlers that bowl with their right hand because the slide pad is on the left shoe, which is the foot you slide with.
Left Handed Shoes: Made for bowlers that bowl with their left hand because the slide pad is on the right shoe, which is the foot you slide with.
Uni-sole Shoes: These shoes can be used for right or left handed bowlers because the slide pads are on both feet.

 

Don't know your shoe size? Do the following
To get the best fit and comfort, we suggest measuring your feet each time you purchase a new pair of shoes because your feet will change during your lifetime.


A piece of blank paper.

A pen or pencil.

A ruler or tape measure.


Put on the pair of socks you intend to wear with the shoes you are ordering. Through the course of the day, your feet will swell so it's best to measure them at the end of the day.


a) With the paper placed on a hard floor, sit down in a chair and place your foot flat on the paper. Lean forward, putting more weight onto the foot you are going to measure. As you probably know, your feet are different sizes so be sure to measure your larger foot.

b) Holding a pencil vertically, place a mark at the end of your heel. Place another mark at the tip of your longest toe.

c) With the ruler or tape measure, measure from the heel to the tip of your longest toe.

To Find Your Width:
Measure the distance between the two widest points on your foot. Reduce this number by 5 mm, or 1/5-inch. The result is the number you will use to determine your foot width.


To find your size, use the inch-to-size table. For example, if you are a man and your foot measures 10" long, you will wear a U.S. size 8 shoe. If you are between measurements, size up to the next larger size. It is easy to add a pair of socks to take up a little extra room but very difficult to make shoes that are too small comfortable.

Note: Just because you are a size 9 in one brand doesn't necessarily mean you are going to be a 9 in another. Footwear sizes and shapes vary from brand to brand. Please keep this in mind.

Description 

Roto Grip Uproar Bowling Ball

 

There’s a brief moment of silence between the time I’m released and when I hit the pocket. It’s a time of reflection… tranquility… serenity. But a split second later, all hell breaks loose. The pins crash, my teammates cheer and my competitions’ egos crumble. Someone grab a mop. Things are about to get messy.


THE CROWD GOES INSANE!

I bring the crowd to its feet and my competition to its knees. My Late Roll 51™ core – the same core found in the Rumble™ – has good length and strong downlane motion that makes my opponents shake with nervous anticipation, all without blowing the budget.


THEY’LL NEVER HEAR ME COMING.

My 51ML™ Pearl Reactive Coverstock allows me to easily clear the front part of the lane and gives me more stored energy down lane. Just when they think I’ve gone too far… BOOM! Lights out!

 

WAS THAT THE PINS OR THEIR JAWS HITTING THE FLOOR?

While my opponents are trying to figure out how to battle too much hook on the front end, the combination of my Late Roll 51™ core and brand new 51ML™ Pearl Reactive coverstock gives me more length and down-lane recovery than ever before in the HP2™ lineup. Medium/light oil conditions? I’m the one you’re looking for.

Uproar by staffer Garrett Richardson
Hand: Left Ball Speed: 16-17mph Ball Weight: 15lbs PAP: 5 left 7/16 up Degrees of Tilt: 17 Layout: 4 &#188; x 4 &#190; x 4 5/16 The Uproar is drilled 1 &#189; inch down from ring finger and cg out with a weight hole down with 3000 abralon. When I first rolled it shined up it was a little too long for me and not much down lane motion, but once I put surface on it the ball came to life but still had the same motion as far as the length when it was polished but an earlier read in the mid lane and smoother transition down lane. I use the uproar when the lanes break down usually after a fresh house shot pattern. When its on more of a fresh pattern I have to stand left and go up the boards until the transition hits then I can move more right. Right now the uproar has been a popular ball for the bowlers who need length with a more controlled back end and not much snap. For a medium to dry lane ball this ball hits like a truck!

COVERSTOCK NAME: 51ML™ COVERSTOCK STYLE: PEARL COVERSTOCK TYPE: REACTIVE WEIGHT BLOCK: LATE ROLL 51™ COLOR: ORANGE PEARL / RUBY PEARL FINISH: 1500-GRIT POLISHED FINISH METHOD: CAN BE SANDED DUROMETER: 73-75 ON D-SCALE FLARE POTENTIAL: 4" - 5"/MEDIUM-HIGH WEIGHTS: 10LBS - 16LBS SKU: RUP RELEASE DATE: 01/07/14 My layout: 4 3/8 x 5 1/8 x 2 My PAP: 4 1/2 over 1 1/4 up If you go back and read some of my other reviews you will see that I have a strong tendency to really like solid coverstock balls. You will also notice that I haven’t given many strong reviews on pearls and hybrids. Therefore when I tell you that I have a high opinion on the Uproar from Roto Grip it should really mean something to you. As I said in the past I am not a big skip/flip type of guy. I like archy ball motions, and I don’t get that with many pearls or hybrids. The Uproar really rolls well for me and became part of my tournament bag very quickly. I don’t get that big skid /flip reaction, and yet the ball does make a very good controllable move in the back part of the lane and accelerates through the pocket. Being that it is a pearl ball I also never have any trouble getting it down the lane. The ball really works well for me when I need to ball down due to transition, The fact that it doesn’t skid/flip, and just archs for me, helps me play the right part of the lane, therefore avoiding the under over reaction I get with most pearls. What amazes more about the Uproar from Roto Grip is it very low price point. I feel you get so much ball for your money that the Uproar should be part of everyone’s arsenal. It will be very hard to go wrong with the Uproar from Roto Grip. The Uproar therefore gets my highest rating.

Roto Grip UpRoar review Mike Johnston
I tested my UpRoar on my 39-foot house shot. The 1500-polished pearl finish worked well for this condition. I pushed the ball to the dry area to gain some friction. My UpRoar is drilled with the pin up above the fingers and a dual thumb hole layout.. I wanted to have a ball that would compliment my Deranged and have a nice skid flip reaction. This ball produced about 3-5 inches of flare. The ball skidded nicely through the heads as I played just inside the oil line skidding out to the dryer boards. Once the ball encountered some friction, it revved up nicely and made a pronounced move to the pocket. ?As with all Roto Grip balls, it drove through the pin deck. The UpRoar has a very predictable reaction, and with the 2.55 RG and .042 differential makes it a great addition for the lower rev medium speed league player who needs the extra length from the polished cover when the lanes begin to breakdown. What I enjoyed the most about this ball is the late breaking skid flip reaction. It produced a nice dramatic hook to the pocket and devastated the pins. What a fun ball to throw. The UpRoar is a nice go to ball for the league bowler and is good compliment to the Deranged and Asylum. This ball will make a nice addition to anyone’s arsenal. Mike Johnston Roto Grip Staff

Roto Grip UpRoar - Louis Narvaez Jr.
Layout 55 x 4 1/2 x 70. I drilled this ball using a 55 x 4 1/2 x 70 dual angle layout. This puts the pin below my ring finger with the cg kicked out. After throwing this ball for the first time all I could say is WOW! Even with this layout the UpRoar made an amazing move off the spot. On the house shot I could move as far left as I wanted and this ball would get down the lane and go left. When I drilled this ball I was under the impression that I would be able to begin moving back to the right when things broke down. The great thing about the UpRoar is that I really do not have to move right. If I am throwing a stronger piece of equipment and it just becomes overly aggressive, the UpRoar allows me to stay in the same spot and keep on going. Here is an example. I was throwing a Hyper Cell at 3000 grit. After about a game the Cell was just too much ball. I decided to move right and throw the UpRoar. First ball BOOM Solid 9 pin. After a few frames I was throwing the UpRoar from the same spot as the Hyper Cell and it was great. The UpRoar pushes down the lane with ease. Don't let the HP2 rating fool you because this ball does move. If you are looking for a ball to use later in blocks or if you have problems getting some of the more aggressive balls to get down the lane this is a ball you should consider. OOB surface on the UpRoar is 1500 Polished. The UpRoar did roll good with this surface but seemed to go a little bit long for me. I hit the ball with a 2000 grit pad to get rid of some of the polish and this ball came to life for me. It also made this ball very forgiving. Louis Narvaez Jr. Storm/RG Pro Shop Staff

Roto Grip UpRoar
Elliott Askey Ball Speed: 18 mph Rev Rate: 450+ PAP: 5x1 up Does a ball ever just tell you to drill it? I had originally planned on waiting to drill my UpRoar until around May for when I go to Nationals. Well, the UpRoar sat on my pro shop shelf for 2 days before I could not withstand the urge to drill it! So I am comparing core and cover numbers with other releases and decide to drill it similar to my IQ Tour Fusion. What a great choice indeed. The ball is drilled with a 5x4 pin up, and it roars down lane. It is a great compliment to the Fusion. It is extremely forgiving and has plenty of recovery left in the tank when I send her a little wide. I messed with the surface just to see how durable the 51 ML Pearl cover was. At 4000, it was an extremely smooth and predictable roll. I believe this is how I am going to leave it for Nats so that I can control the breakpoint. At 2000, well, it wanted a little more oil than I was seeing on our 39 ft THS. The UpRoar is a great benchmark piece that will fill that mid level performance hole you have in your bag!
