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.

Description 

Roto Grip Dare Devil Danger Bowling Ball


On the outside you will find the proven Psyched Hybrid reactive cover. Comprised of 2 parts pearl & 1 part solid, this cover will provide length through the front of the lane and offer a more predictable reaction off the friction down lane.

On the inside you will find the strongest rolling low RG symmetrical core that Roto Grip has ever offered. It was introduced originally in the Dare Devil and more recently used in the Dare Devil Trick.

Ideally this ball is built to battle a variety of oil patterns, but ideally it will excel on those medium type conditions. It comes out of the box shiny, but it can be sanded to battle more oil. Given the success of the Dare Devil and Dare Devil Trick, this ball will give you just a little bit different motion down lane and provide the pin action to make your opponents shake in their shoes!

Roto Grip Dare Devil Danger Ball Review by PJ Haggerty
After drilling with the Roto Grip Dare Devil (pearl) and Dare Devil Trick (solid), creating a hybrid version would be a perfect addition to the HP3 line. The core hasn’t changed (RG of 2.48), but the cover is no a Hybrid version to create more length than the Trick, but the Danger provides and earlier motion than the first Dare Devil. I’ve drilled all three Dare Devil balls very similar and had success with all of them. This one is mapped out as 5 ¼ x 4 ½ with a small hole two inches under my axis. I’ve mainly used the Danger on medium-longer patterns because of the low RG numbers in the core and also tweaked the surface to 2000. The cover is still clean, but the surface helps slow the response time down and create a more predictable shape. I’ve noticed the Danger is cleaner and more responsive than the No Rules Exist, but stronger than the All-Out Show Off and Hustle Line. Go drill one! #OwnIt

**DANGER**
This ball is a great compliment to the original Dare Devil and the Trick. The Danger allows me to get that little extra angle and pop off of the spot where the Dare Devil and Trick are smoother off of the friction. I can start with the Trick and then go to the Dare Devil if the heads are burning up and need that extra length down the lane but if it gets too clean or flat I can grab the Danger and open up the angles. The trio of Dare Devils are definitely a great Arsenal starter. You can't go wrong with them in your bag.

RotoGrip DareDevil Danger
The RotoGrip DareDevil Danger is the third release in this HP3 series. The MadCap Core is back and wrapped in the Psyched Hybrid cover. The DareDevil line has been a strong series of bowling balls from Chris and the crew. Each release is very unique on their own, but as a team, they work really well together. I drilled my ball testers Danger, Keith Demaine, with a very controllable layout. It was a 2 1/2 inch pin just outside and under his ring finger, with the CG just outside and below his thumb. We were looking for a condition specific reaction from this ball and we got it. The Danger was pure arc down the lane and unfortunately with time against us the day of shooting, I could not get a sport shot out on the test lane. The video does this ball no justice….with as smooth as the reaction was, Keith’s rev rate and speed on a walled up house shot, the roll was not impressive. It struggled to turn the corner and hit pretty weak…again, we drilled it with shorter sport conditions in mind. Keith used it later on a shorter 3 to 1 pattern and his reports back were excellent. The DareDevil Danger is exactly what you’d assume as a perfect middle ground between the OG DareDevil and the Trick. Once again, great Job to SquadRG! #ownit

Dare Devil Danger
The Roto Grip Dare Devil Danger has the Madcap Core, which is also found in the original Dare Devil and the Dare Devil Trick. The Psyched Hybrid reactive cover is designed for length in the front part of the lane while controlling the response to friction down-lane. Where a lot of shiny balls with easy length have uncontrollable sideways motion down-lane, I don’t feel like this ball has any erratic behavior to it at all. You can see it read the mid-lane to slow itself down a bit and then it unloads on the backend. I have thrown it on 43 – 46 ft house patterns and burnt up patterns as well and I have found it to work nicely on both, as long as you can continue to move left into more oil. I went with a 55 x 5.25 x 45 layout which puts the pin above my middle finger. I think this is a logical transition ball from the Dare Devil Trick when the duller surface of the Trick starts to hook a little too quick and flatten out at the pins.

Dare Devil Danger
Weight: 14 lbs. Pin Length: 3.5” Drilling: 30 X 3.5 X 20 Pattern Length: 39 ft. Pattern Volume: Medium Pattern Type: House Right Handed The Dare Devil Danger has the Madcap Core wrapped in the Psyched Hybrid reactive coverstock. It has a very attractive Red/Orange/Blue shell. This ball comes out of the box at 1500-grit polished, with a medium to high flare potential. The cover can be sanded for earlier hook and roll, or left at box if you’re looking to complete your arsenal with a ball to give you more length and good snap off the pattern. I have used the Dare Devil Danger on house patterns and on a modified tournament shot of 41’. For our 39 ft. house pattern,I used the Dare Devil Danger at the 1500-grit polished, box finish. It got through the heads better than I expected, and finishes much stronger off the pattern than i anticipated, continuing through the pins. As the pattern transitioned, I was able to move in and still carry the corner pins. On our 40 ft. house pattern, I, again used the Dare Devil Danger at box finish and it was still strong enough for the shot. I was able to play a little further out, more in my comfort zone, on the longer pattern. This ball saves it’s energy for when you need it most. Right through the pin deck. On the 41 ft. modified pattern, i hit it with 2000, no polish. This smoothed out my reaction, gave me an earlier roll and set up nicely for me. When the lanes transitioned, I went to the pearl Dare Devil and was able to stay in the same zone. The Dare Devil Danger is a great ball in the popular Dare Devil line. It is a great complement to the Dare Devil and Dare Devil Trick, filling that spot right between the two in my bag. The Dare Devil Danger is a fixture in my arsenal these days.
