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 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.

Roto Grip Show Off Bowling Ball


DEMAND AN AUDIENCE... Don't be scared... It's OK to be noticed!

CORE...
Created from logic, the brand new Hotshot Core was designed to provide length and down lane motion. Safe to say we nailed what we set out to do by maintaining a lot of bang for the buck in the HP2 price point!

COVER...
This cover was first introduced on the original No Rules and will tackle any amount of oil you wanna throw its way. This cover can be sanded more for those heavier oil conditions just like the No Rules.

CONDITION...
The intention of this ball was to create that ideal "step down" when the conditions call for it. It will allow you to stay in the same zone you were playing with the stronger balls, but because of the higher RG core, it will clear the fronts much easier and grab as early. Or it can be used on the fresh when the backends are crisp and you need a stronger motion that won't go sideways down lane.

Roto Grip Show Off
I am a left handed and a Storm/Roto Grip Regional Staffer. I throw the ball around 15-17mph. The first Show Off I drilled I put the pin above the Ring Finger and the CG is stacked. The surface I kept the same as out of the box which is 2000 grit. The Show Off has the Original No Rules Cover with a new Hotshot Core which is designed for Length and Back End Reaction. I will tell you that this ball is special and is more bang for the buck. If you want a ball that is strong and you don't want to spend $200.00, then this ball is all that you need. This ball is great on THS, and Medium to Heavy oil pattern. Roto Grip has mastered this line as more ball for the price you are paying. The HP2 line has produced a lot of Fantastic balls and The Show Off is another one. I compare the Show Off with the Haywire and the Show off is cleaner in the Midlane and more Back end then the Haywire. The first game I threw the Show Off was a 300. The Show Off to me is a really strong ball that I can use on multiple lane patterns and I can manipulate my hand position with this ball when the lane changes and I can still use this ball. This ball is a must for anyone and it does not matter how you throw the ball. So get to your Local Pro shop and purchase a Show Off. You will not be disappointed. #showoff #ownit Doug Cutler Storm/Roto Grip Regional Staffer PBA Regional Champion

Roto Grip Showoff
The Roto Grip Showoff was much stronger than expected for an HP2 line ball. Its a perfect benchmark ball for anyone regular league bowler. I was really impressed with the way the ball read the front part of the lane and then with the motion and energy it stored on the backend. Its strong enough that on heavier oil patterns you can square up and get it to the pocket but also smooth enough that on dryer conditions you can move in and go around it and it doesn't roll out. If your looking for a smooth with aggressive back end motion ball this is the perfect fit.

Show Off Bowling Ball Review
Today im doing a quick review on the new show off from roto grip.When i found out about this ball coming out i was pretty excited to see a ball like this casue i felt roto grip needed this in there line up.I belive very good bench mark ball to have in every bowlers bag.great price point as well.When throwing this bowling ball i can see it have great midlane with good controlled backend.works very well on more longer volume patterns.I can for sure see bowlers who need a little more help,speed dominant and less rev players for sure can get this ball to hook no problem.really like colour choice and name always awsome to see what roto grip comes out with always excites me lol.also a ball you can adjust the service no problem to fit your needs.So dont wait go out and drill your show off today.

Roto Grip Show Off
The Roto Grip Show Off has the original No Rules cover with a new core designed for length and down lane motion. I think that this is quite an interesting combination with the potential to possibly be the strongest ball ever made at this price point.  Historically, I have absolutely loved the HP2 line, but there is nothing about this ball’s motion in the midlane and back part of the lane that says HP2 line. On a fresh 43 foot typical house pattern it is definitely straighter than my No Rules Exist, but as the lanes break down and angles get a little too extreme for my Exist to maintain optimal entry angle, this ball shines. My Show Off’s layout is 3.75 x 5.75 x 1.875 and is still at box (2000). Chris Freeland

Show-Off
The Show Off is the newest solid cover ball in the Roto Grip HP2 line. It has the Hotshot core with a 2.55 RG value, a .045 Diff and the Micro DNA solid coverstock. So it has a core that should respond quicker than average to friction and a fairly aggressive coverstock. I drilled mine 4.25” from my axis with a 2.5” pin buffer and low p3 hole. Hoping this would be my go to on medium volume, medium length patterns. This ball for me rolls like a strong benchmark ball. It is smooth and predicable on the back and is not too clean on the fresh. I am surprised with how much hook the Show Off has for it’s price point. I found the cover to be pretty strong, so unless you are speed-dominant, it probably will not find its way to the lane for light oil. But when the Dare Devil Trick or No Rules Exist are too early, this ball is PERFECT.
