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 the lane 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 bowling 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.

1. Get a blank piece of paper, a pencil and a ruler or tape measure.
2. 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.
3. 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.
4. Holding a pencil vertically, place a mark at the end of your heel. Place another mark at the tip of your longest toe.
5. 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 Winner Bowling Ball


CORE...
Starting the with the same shape from the original Hotshot™ Core, we changed out the slug on bottom to totally change up the core dynamics. With a heavier slug, the RG value went down just a touch, while the differential went up almost 10 points. Lowering the RG and increasing the diff = more downlane change of direction!

COVER...
The newest formulation of pearl coverstock known as the VTC-P18™ brings a new level of versatility to the HP2 line. This formula increases traction throughout the entire lane while still retaining energy for plenty of down lane responsiveness.

CONDITION...
This ball is hands down the strongest pearl ball ever released in the HP2 line. It will show its super powers on those Medium type conditions but can easily be scuffed to tackle a little more oil if need be. Lets just say the name fits the performance and results you will get with this ball perfectly!

Roto Grip Winner
I drilled my Roto Grip Winner 5.5 x 5 x 3. Compared to my Storm Match Up Pearl, the Winner gave me a similar motion with more over-all performance. The Match Up Pearl was my go-to ball when I started to see friction either in the front part of the lanes or just overall lane play. The Winner will be a bit more versatile because of the slightly stronger cover and core. While throwing the Winner, I noticed that on almost every shot, it continued to drive through the pocket and never deflected off the pocket. If you’re a tournament bowler or just searching for a good overall league option, the Roto Grip WINNER is the clear choice.

BACKEND!
Roto Grip Winner The Roto Grip Winner is the newest ball in the HP2 line. It features the altered Hot Shot core, which is a slight variation of what is inside the Show Off. And also has the new VTC – P18 Pearl reactive cover stock. The Winner is one of the cleanest and strongest down lane shapes I have seen from Roto Grip in a long time. It really likes to get down the lane and have a strong change of direction at the back end of the pattern. If you’re looking for that skid snap shape the winner is the ball you need!

RG Winner by Matthew Kemper
Roto Grip Winner Ball review Review: LANE CONDITION Lane Type: Wood Length: 41ft Volume: 21ml Type (THS, Sport Pattern etc): THS The Roto Grip Winner is Roto Grips newest HP2 release. The Winner contains the Altered Hotshot Core which is symmetrical. The balls cover stock is the VTC-P18 and is finished at 1500 grit polished. I drilled my Winner with my favorite and most used layout. The pin is to the right of my ring finger giving me a 3.5 inch pin to pap distance with the CG stacked below the pin. The combination of this layout with the Winner has given me a straighter more smooth reaction on a weaker ball. The winner is very similar to the Roto Grip Hectic but the Winner is about 3-4 boards stronger. The Winner is very long with more of a back end reaction but the Winner doesn’t have a jerk reaction off the spot. The reaction off the break point is much more controlled and has a very heavy roll through the pins. The ball is very clean through the heads which allows me to move in with it as the lanes allow. I am a big fan of these HP2 balls because they allow me to stay straighter early but they have a strong enough reaction that I can move in and still keep my carry power. I recommend the Winner for House Shot leagues and medium volume sport patterns. They Winner like most HP2 releases are very versatile and stronger than it probably should be but that’s what makes them great. The Winner is about 5 boards weaker than the Dare Devils so its definitely something you can ball down too later in tournaments.

RG Winner review by Brian Watson
The new Roto Grip Winner is a great addition and a missing motion in the current line. I drilled mine 5 x 4 x 4 pin down. I hit it with a 4000 abralon pad to take a little shine off as it is very clean through the fronts. Ive been able to use the Winner on pretty much any lane condition so far. I drier house shot it really shines! I bowl on a couple sport patterns also with success, but it needs to have the surface altered to around 2000 grit to get the best reaction. But it has the great RG reaction down lane with it rolling or (tumbling) off of the breakpoint. Very controllable and predictable. Brian Watson PAP - 3 5/8 up 1 1/4 Speed - 16-17 Tilt - 17 RPM - 400

Roto Grip Winner
The Roto Grip Winner is the newest additions to RG’s HP2 Line. Like most of their HP2 line balls, you cannot beat the “bang for your buck” performance that they offer. I laid this ball out 5.5x4.5x40 and tested it out on a typical house shot. What I found was a very Wrecker-Like ball motion. The Winner glides effortlessly through the front part of the lane. The backend motion was not exactly a “flippy” motion, but rather a continuous roll. As clean as it was through the fronts, I was expecting a lot more snap, but was pleasantly surprised when I saw the motion on the backend. The energy it stores really shows when it goes through the pins. Off hits sent messengers, light hits carried with ease, and anytime I was close the ball ran em over. Go to your proshop and pick you up one of these today!
