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.

Crux Prime Ball Review
Here today to do a ball review on the storm crux prime.The storm crux prime is using s-pec solid cover stock with a 2000 grit finish.After drilling one I can see where this ball can fit in alot of bowlers bags.I was really liking the original crux the roll and shape this ball had when is was going down the lane,now with the prime you can tell this ball is alot sooner but down lane alot smoother shape,not to jumpy of the dry as the original crux.Plus I really like how colourful this ball is when going down the lane you can tell from anywhere in the bowling ally that's a crux prime lol.Great ball to start with and very good for more volume patterns,ive also took it down to 1000ab and you can tell this cover stock likes to chew threw the oil with ease.Bowlers with little more speed can benefit with a ball like this.

Crux Prime by Roto Grip Rick
Storm Crux Prime – 50 x 6 x 50 – 14lbs. Spec solid coverstock – 2000 grit – 6” plus flare The final ball added to my new 14lbs. arsenal is the Storm Crux Prime. Drilled for SPL and Brunswick lane panels I have been practicing on since my return to the sport a few weeks ago since my accident last year. I started with weaker stuff and working my way up to stronger stuff and found that this ball was WAY too much on the THS I bowled on normally. My home center is older HPL and a hard cliff at the end of the pattern, there is 2 other centers I like to bowl at and one has newer SPL and the other has really new Brunswick panels. With the RA value of the SPEC cover, it cuts through all the heavier oil and still has plenty of energy left to recover on the backends. To see conditioner sit on this ball for several seconds and it NOT soak into it was COMPLETELY amazing. Best heavy oil ball I have used in a while that has not diminished in performance over the past 30 games I have used it.

Crux Prime by Matthew Kemper
The Storm Crux Prime is Storms newest Premier Line bowling release. The Crux Prime contains the Catalyst Core which is found in all of the Crux line of balls. The Prime is covered by Storms newest cover stock called the SPEC Solid Reactive cover. The ball is factory finished at 2000 grit. First off I want to talk about the new SPEC cover stock. The SPEC cover is designed to fit the new USBC rules for oil absorption. This cover is amazing. I’ve thrown a few practice sessions and 5 games at the USBC Open with it already and the cover still looks and feels dull like it did brand new. I can’t wait for this cover to be available on future bowling balls. I drilled my prime pin down and stacked below my bridge. I drilled it specifically for Nationals. I wanted a good strong ball that can handle oil but with a layout that will roll earlier and stay smoother down lane. This is exactly what I got. This layout combined with the cover really helped me control the back end reaction on the tough USBC Open conditions. I found some success early with the Prime but when I started to have to migrate left, the ball because to strong in the front part of the lane where I had to ball down to get more backend reaction. On house shot conditions I’ve found the Prime to be very strong and the ball hits like a tank through the pins. Despite my layout choice I still find the Prime to have a good amount of backend reaction which makes it great for medium to long patterns and heavier volume of oil. For me the Prime is quite a bit stronger compared to the original Crux and Alpha Crux. I recommend this ball for anyone looking for a ball that can handle oil and who is not afraid to get left and loop the lane. This ball will cover may different types of oil patterns except maybe short patterns but its very versatile.

Crux Prime
My name is Doug Cutler and I am a Storm Staffer and I have had drilled 2 Crux primes and man both of these balls are awesome. My First Crux Prime I drilled 70 x 4 1/2 x 35 and the surface is 4000 grit. This ball I tried out of the box but man it was really strong and for the shot we were bowling on I had to bring the surface up to 4000 grit and man this is the ball I use right out of the bag. I am able to stay left early and keep my ball speed up and I am able to use this ball for about 2 1/2 games and then I go to my Pin down Crux prime and move right and open my angles up. This ball with this layout I can use it on THS, and Medium to Heavy Oil Patterns. My Second Crux Prime I drilled 45 x 4 1/2 x 70 and the surface is 3000 grit. This Crux I really like when there is carry down and man this balls does not read to early and it save more energy in the back and has a lot of shape and man it hits hard. I use this crux on Medium to Heavy Oil Patterns and you can use it on THS. I would say that this would not be a ball for short oil patterns. I have used these 2 crux primes a lot and if you liked the original crux you will love this crux also. This is a ball you will definitely need in you ball, so get to your local pro shop and purchase your Crux Prime if you have not gotten one yet. Storm hit another home run with this ball. #stormnation #cruxprime #bowlupastorm Doug Cutler Storm Staffer PBA Regional Champion

Crux Prime
This ball is amazing! For being an asymmetrical solid ball, I am able to get left without losing much energy. I drilled mine pin up above the bridge. Typically, I can only play 10-15 before I need to switch to a pearl to save energy, but with the Crux Prime, I can play left of 15 easily. You can use this ball on any pattern. I've used it on THS, and medium-long sport patterns on the PBA. I for sure recommend this ball to anyone looking for a strong dull ball. You will not be disappointed! #StormNation
