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.
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 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 followingTo 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.
A piece of blank paper.A pen or pencil.A ruler or tape measure.
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.
a) 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.b) Holding a pencil vertically, place a mark at the end of your heel. Place another mark at the tip of your longest toe.c) 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.

Technology The Radical Inferno® is the first ball to take full advantage of Brunswick’s new Urethane casting machine. The machine is part of a custom built “State-of-the-Art” room full of high-tech equipment that incorporates enhanced control over processing parameters. This machine includes a sensor system that monitors temperatures, pressures and flow rates at every important point in the casting process. Our new mixing head is multi-color and particle capable. This all new system allows the Brunswick R&D team the unprecedented ability to fine tune bowling ball performance. Octane Coverstock Our new Urethane casting machine has enabled Brunswick to produce a new class of Reactive coverstock. Octane coverstock is the result of 3 years of Research and Development into both materials technology and Urethane processing parameters. The same meticulous screening of materials that produced the Activator coverstock family has now resulted in Octane. Improved back-end traction with a sharper breakpoint, Octane is a perfect complement to the Activator coverstock balls known for their early revving ball reaction. Reaction Characteristics The Radical Inferno is in the highly angular ball reaction class with a high traction breakpoint that is sharp, powerful and continuous. With its high gloss polish surface the Radical Inferno gets down the lane and through the heads with ease. What is unique about the Radical is its ability the make a sharp, continuous turn to the pocket with more traction at the breakpoint. Our ball test group has commented at length about their ability to keep their speed up with the Radical Inferno, without the ball losing traction down lane in heavy oil or heavy carrydown. The Radical is the best they have ever seen in a highly polished Brunswick ball. Utility
Out of the Box: With its High Gloss Polish finish the Radical Inferno will match up well on medium-dry to medium-oily conditions.
When dulled: The Radical Inferno hooking action will increase and its arc will become more even, creating a better match-up for oily lane conditions and help blend the over/under reactions seen on wet/dry lane conditions. The testing program for the Radical Inferno has identified two favored surface finishes. One is the Factory Finish High Gloss Polish that is being used on the Radical. The other is a dull, but very smooth surface typical of Scotch Bright White Pad or Abralon grits of 1000 or greater. If you bowl on a lane condition where your Radical Inferno goes too long and struggles to make a strong backend move, Brunswick strongly recommends that you remove the polish from the ball with a burgundy Scotch Bright pad, or similar aggressive abrasive, then use the Grey and White Scotch Bright pads, or the 500 & 1000 grit Abralon pads to create a dull, but very smooth surface finish.
