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.

Roto Grip Halo Bowling Ball


Centrum Core...
Using a "cube like" shape as a starting point, additions and subtractions were made from there. The key being the radial disc shape added to the middle body of the core to increase the rotation/continuation of the core once in motion. This part took countless man hours and over 1 full year in development to become a reality.

Cover...
The MicroTrax-S18 formulation was first introduced on the IDOL™. This coverstock continues to be tested by our R&D team to ensure we haven't missed anything. To date, this blend still stands as the strongest solid coverstock formulation Roto Grip has ever introduced.

Condition...
This ball was created to destroy and conquer the heaviest of conditions. By pairing the new super strong Centrum asymmetrical core with our strongest traction coverstock to date, the new HALO is a bowling ball revelation that is second to none. If you liked the original Hyper Cell™ or the original No Rules™, then this ball is for you! Think that same type of motion ONLY STRONGER!

Roto Grip Halo
This ball FLAT OUT HOOKS! After throwing the Roto Grip Idol earlier in the year, I thought to myself, wow, this ball hooks. Now a few months later, the new Halo from Roto Grip hooks even more. I drilled mine with a 5 x 5.5 x 1 layout putting the pin high above my fingers. I choose to go with this layout because I was worried about the super strong cover and core burning up too early. The Halo will easily give you 6 to 8 boards more than the Idol. This will easily make the Roto Grip Halo your first option on long patterns. If you are looking for a ball that loves oil, look no further than the new Halo from Roto Grip!

Roto Grip Halo
First of all, I love this ball! The Halo hooks a ton for me and still has drive through the pins which I can't find with the higher end solids. I tried the Halo on a few different patterns and found for me I needed to start in between the 3rd and 4th arrow but started moving left pretty quickly on the house and some challenge patterns. I really like how versatile this ball really is. I even tried playing over the 6th arrow just to see how this thing rolls and I was shocked how it didn't lose its drive or roll out early. I usually don't play that deep with a solid but with every ball you need to find that breaking point to see how far is to far. I strongly feel that this is a must get in the bag for those who need an aggressive ball.

Halo Hooks!
Roto Grip Halo The new Roto Grip Halo is in the HP4 line and features the strongest core and cover stock combination that Roto Grip has to date. When I threw the halo it was exactly what I was hoping for… It hooks! This ball needs oil in the front part of the lane. At first blush the Halo gave me flashbacks of the original Cell. The core transitions very quickly and delivers a very strong predictable motion. Since the Halo and the Idol have the same cover stock I decided to compare the two. And heavy oil, the Halo definitely picks up earlier. The Idol has more backend but the Halo picks up a bit quicker in heavy oil when the Idol wants to push.

Roto Grip Halo Ball review Review: LANE CONDITION Lane Type: Wood Length: 41ft Volume: 21ml Type (THS, Sport Pattern etc): THS The Roto Grip Halo is Roto Grips newest HP4 release. The Halo contains the Centrum Asymmetrical Core. The Halo is covered with the MicroTrax-S18 cover stock and is finished at 2000 grit matte. I drilled my Halo 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 Halo is an amazing ball. The Halo makes my misses look great. It is a very strong ball that recovers well when I miss right. The balls overall reactivity is very similar to the Roto Grip No Rules. The biggest difference for me is how well the Halo gets through the heads where for me the No Rules really wanted to roll early and flare out if the lanes didn’t have enough oil on them. For myself, the Halo is the most versatile High end solid I’ve ever thrown. I can play straighter with it on heavy volumes and can get inside and really trust the ball to make the corner while still have energy left to carry the pins. The cover stock is strong and if you hit up on it early or get soft the ball will over react. I recommend the Halo for heavy volume patterns whether its sport of house shot. I feel like you can adjust the layout or cover to fit what you are looking for but the Halo is great for starting on fresh and then switching to a pearl to keep going.

Roto Grip Halo Review by Brian Watson
The new addition to the Roto Grip HP line is the Halo. Solid coverstock with an Asymmetrica core. I drilled mine 4 x 6 x 2 pin up. I have from other staffers and bowlers that the Halo reminded them of the Storm Alpha Crux and a beefed up IDOL. I personally can see those motions in the Halo. The Halo is cleaner through the fronts than I expected with the solid coverstock. I compared the Halo to my Storm Lock and the Halo was at least 3-4 boards weaker for me. But for me the motion was very good midlane motion with a strong arcing motion at the breakpoint. The best thing I saw was how low it keeps the pins and the carry was very good. So if you like the IDOL and just need a little more ball strength the Halo is your ball. Brian Watson Storm Pro Shop Staff PAP - 3 5/8 up 1 1/4 Speed 16-17 Tilt - 17 RPM -400
