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 

Storm Crux Prime Bowling Ball


The design almost every Storm PBA tour player was demanding to be brought back. With the Catalyst Core, you, too, will bear witness to unprecedented power, increased entry angle, and a greater margin for error with its dynamic asymmetrical design and vertical cavity technology. The benefits of SPEC Solid Reactive can be truly appreciated on heavier conditions, especially when they begin to transition. When this coverstock encounters midlane friction, it digs in harder, unlike anything Storm has produced to date.

In the heart of the ball lies the innovative Catalyst Core. The genius the design is in the cavity which lets the driller remove less mass with most layouts. No more second guesses or shots in the dark. The ease of drilling is self-evident in this design.

SPEC stands for “Storm Performance Enhanced Coverstock”. The intent behind this formula was to create something that withstands the rigors every bowling ball endures each time it takes a trip down the lane; namely, the friction and oil it encounters. We all know and accept that bowling balls smooth out over time, just like the tread on the tires of your car. With SPEC, you can expect consistent performance that is as tireless as it is dynamic. It’s bold, definite, and extremely potent.

Storm Crux Prime
The new Crux Prime by Storm picked up right where the Alpha Crux left off giving Storm that dominate asymmetrical ball at the top of their line. Having never thrown the Alpha Crux or Sure Lock, I choose to Compare it too the Roto Idol Solid, the Crux Prime actually gives me a similar motion as Idol but in a stronger motion. If you loved any of the Crux’s and especially the Alpha Crux, you will absolutely love this ball.

Storm Crux Prime
Layout: 55 x 4 5/8 x 55 The Crux Prime has surprised me, in that it has become of my favorite bowling balls that I have thrown in years. I did not expect this super strong high end ball to be as usable at it is. I did hit the ball lightly with some polish before using it, so that I could mimic the lane shine that would usually show up after 20-30 games. My intent with doing this was to conserve the energy through the front part of the lane better, which it did. This ball is still quite strong, even with the surface adjustment, but I have no qualms with moving left and circling the lane a bit when the lanes break down. Having said that – this ball is in no way at home on drier lanes, but as long as there is some oil in the front part of the lane, this ball is a treat. Out of box it could handle the heaviest of heavy oils. The midlane traction is very strong, but the ball continues through the pins very well. Amazing ball on anything medium oil or heavier!

Crux Prime review by Chris Szczepaniak
The Crux Prime by Storm is hands down one of the first balls out of my bag for tournaments or anything with longer patterns. The all new SPEC coverstock (Storm Performance Enhanced Coverstock) is one of the strongest and most forgiving I have ever seen. This added with the proven Catalyst core make for a very heavy, smooth rolling ball. I matched this with my favorite layout of 60x5x40 (PAP 5 3/8 up 3/8) and was blown away. This ball not only looks amazing going down the lane but hits like a tank. With the way I have my arsenal set up my Physix (same Layout) is a perfect ball to ball down to. The Crux Prime just seems to get better and better the more games you have on it. Of course with any dull ball it is very important to make sure that you stay on top of your surface management. I already have another one coming and cannot wait to throw it with my favorite pin down layout.

Crux Prime review by Tommy Gollick
The Crux Prime is the latest high performance bowling ball in the premier line from Storm. The Prime uses the same Catalyst core that was in the previous Crux balls, but this time, wrapped with an all new to the industry cover stock formula called Spec. This new formula of solid reactive material produces a lot of hook, with less oil absorption than other formulas and comes from the factory with a 2000 grit abralon finish. In a nutshell, the Crux Prime is a big hook ball that is also built to last. The Prime has an Rg of 2.50 with a differential of 0.052, and intermediate diff of 0.017, in 15lb bowling balls. I drilled my Crux Prime using a 4 x 4 x 3 layout. Comparing the Prime to a Physix with a 4 x 5 x 3 layout, both balls were in their respective factory finish, although the Physix has about 35 games on it. I drilled the Prime and went to league the next night with an open mind and no expectations. I had been using the Physix, and been doing very well on this higher volume house condition, and posting a 300 with it a little bit back. I started with the Prime, which I had to move in about 3 & 2 with my feet/mark, to keep the ball holding pocket, compared to the Physix. All I could say was WOW! The Prime read the pattern perfectly for two games, posting a 279 and 245 without moving my feet. Then game 3, 168. I stayed in one spot WAY too long, and by the time I moved, I was playing catch up the rest of the game which turned into Splitsville. The next set I threw the Prime, I learned from my previous mistake of staying put. I decided to gradually move in with it as the 3 game set went on, shooting 258, 237, 278 for a 773. What I learned about the Prime, is that this ball will be a beast for me when I can use it in PBA where we move every game, and generally don’t see as much traffic as the right side of the lane gets. When bowling on high traffic conditions, know when to move with it, or just put it away and grab something else. The Prime also rolled great for me on the 2012 PBA Detroit Open pattern that is 42 feet long, with total volume of 25.5ml. I was able to stay put for three games on this pattern, and not see that huge breakdown at the breakpoint like I saw on the league condition, posting blocks of 673, 653, and 664, on the fairly flat sport pattern. I polished the Prime with Storm step #1 to see how it rolled with less surface, and it looks great on USBC White pattern #2. In summary, the Crux Prime has a very unique ball motion. It takes changes to the cover very well, and doesn’t seem to lane shine as quick as other super strong covers can. The biggest thing with the Prime, is to know when to make a move, or when to go to a different ball. The motion that it makes can sometimes trick a bowler into thinking they can stay in one spot longer, then they really should. This will be a great ball for bowlers who watch what is going on with the lanes throughout the night, but could possibly mislead a bowler who isn’t watching for transition. Thank you for taking the time to read my review of the Crux Prime. As always, bowl up a Storm!
