Hello,

Except a few, most bowlingballs under 14lbs have different cores than the ones at 14-16lbs.

Brunswick has two different cores for those weights and also shows the numbers for them (RG, Diff).

What about other companies like:

- Storm (Dimension)
- Ebonite (Pinslasher)
- Columbia (Resurgence, Rival)

Does someone know more about the cores they use and there dynamics?
You would help me a lot, because I'm looking for a symetrical 13lbs solid reactive with low RG and medium diff.

Thanks,

Antoine

I THINK Storm uses the same SHAPE core in their Premier/Master/Crown lines for 12 and 13 lb balls. The difference is in the core densities, I believe.

Not sure about Ebonite or Columbia. I think I remember someone posting that they use a light bulb shaped core in 12 and 13.

Medium differential should be easy, the problem with a low RG ball in 13# is the coverstock is pretty much a set density. The lighter the ball gets, the more mass there is being removed from the core/center of the ball. This results in it being very difficult to get low RG in lighter weight balls.

Black and Red Bash from Ebonite appears to have the lowest RG in 13#. @.50 and 0.030 for diff.

Be forewarned though... it's in these lightweight balls that shops see a lot of cracked balls due to moisture absorption.

It will vary from company to company and ball to ball. Some, especially smaller companies like Morich and 900 Global, will simply not make lighter weight balls. Others will put a different core in lighter balls.

Storm has made a lot of their older Master line balls (back in the X-factor and Paradigm days) with a simple lightbulb core in the 12 and 13# versions. Track used the core from the Crunch Time in a lot of their higher end light weight balls that had fancy asymmetric cores in the heavier weights.

Other balls from Storm and Track simply weren't available in 12 or 13#.

In the end, if you need a light weight ball, there's no real rule that you can go by. You can't say "Oh, I'll just get a ball from Company X since they put real cores in the light balls". Sometimes yes, sometimes no. As you said, Brunswick seems to be pretty good about publishing that info for others you might have to contact the company to find out.
