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 Idol Pro Bowling Ball


Inside you will find the now famous Ikon Core. This is by far the best low RG / high diff symmetrical core we have ever offered in the HP3 line. It provide plenty of flare and continuation.

On the outside you will find our newest solid creation in the eTrax-S19 cover. This formulation was created over the last couple months to create more traction in oil without reading the lane too quickly. Then we finished it with a Sheen which means we factory polished it and then scuffed it with 3000 before we boxed it.

Bottom line, this ball is just different. We decided to make this a "Pro" version by way of the coverstock finish. The 3000-grit Sheen marks the first time we have ever offered this at Roto Grip. In our testing we found this formula of solid with a sheen finish creates push through the front of the lane with more control at the breakpoint. Compared to a shiny IDOL, the IDOL Pro has more shape down lane because it does not have the added nano particle in the cover.

Idol pro
The Roto grip idol Pro is the newest idol to one of the most successful lines in the Roto grip line. When I drilled this ball I didn’t know what to expect since I drilled an original idol I drilled it to smooth and wanted something different so I drilled pin down and it’s my favorite ball in the bag. When this ball gets in the mid lane and starts rolling it just continues and continues through the pocket. I have drilled a few of these for some people and they are all in love with the continuation. So if you need something that just keeps on going and continues this is a ball for you. Also on sport patterns this is a ball I use a lot when I can with my rev rate declining and speed this is a ball that helps me get through the heads clean and I can get to rev up and continue.

RG Idol Pro review by Mike Craig
PBA50 member - 14* axis tilt, 35* rotation - 16.5 mph - 315 rev rate. I drilled my Idol Pro 4 3/4" x 35*. I have been putting 2000 or 3000 depending on what pattern I am using this on. I get a smooth benchmark type reaction out of the Idol Pro. It has been a great ball down option for me when my Halo is getting sluggish at the spot down lane. The Pro pushes thru the front retaining energy well. i drilled a second one with a 4" x 25*. The second one might be too strong of a lay out. I may have to scratch that one with more surface and use on longer patterns.

Idol Pro
Roto Grip’s HP3 line has been one of the most popular lines in bowling in recent years and this release doesn’t disappoint either. I drilled my Idol Pro just like my original Idol and Idol Pearl, 5 x 5 x 3. After throwing the Idol Pro from some time I quickly realized why I love throwing these balls so much. Compared to the original Idol the pro gives you the same overall ball shape and motion just a touch weaker because of the cover difference. The Idol Pro is much stronger compared to my Idol Pearl. If anyone liked either of these two bowling balls your not going to want to miss out on this ball !

Roto Grip Idol Pro Review
Roto Grip’s welcomes its new HP3 ball the Roto Grip Idol Pro. The Idol Pro has the eTrax-S19 coverstock with a 3000 grit sheen finish wrapped around the Ikon Core. This same core was featured in the Roto Grip Idol which is a lot of bowlers favorite bowling ball for a benchmark bowling ball. This new Idol Pro is not quite as early as the Idol but still has the same smooth continuous motion downlane. Personally this is one of my favorite balls right now just because of how versatile it is on multiple lane patterns but especially for medium-heavy oil patterns.

Idol Pro
This Roto Grip Idol Pro is by far the best ball I have ever thrown and that is not a lie !!! Hands down the reaction I get the way it goes through the pins is insane. I have been using this ball on my house shot to start the season and the scores I have been putting up shows how good it really is. I found that for being a solid i get good push through the front part of the lane , but packs a big punch on the back end. Going to my original idol I had to move three and two right as the OG Idol would not make the corner like the Idol Pro. Idol will be a great ball down for me. I have been recommending this ball to everyone !! You won’t be disappointed.
