13 pound balls
« on: March 05, 2018, 07:59:32 PM »
Hello,
    My wife is ready to move up to a 13 pound ball.  I believe not all 13pound balls have the same, high performance core as balls 14lbs and up.  Is there a good list somewhere of 13 pound balls with great cores?  Is the fact that a 13 pound ball may not have the high performance core advertised by most manufacturers?  Any help would be appreciated!

Thanks

Mike

Not all the manufacturers do a good job showing you the cores in all weights but almost all of them at least list the diff numbers at the various weights.  Usually when they go to a generic core or no core you will see a big jump down in diff.  Went through the same thing for my wife but had to search hard to find her a 10lb ball with a core.  Settled on a Blue Hammer.  The Ebonite Cyclone also uses the same core all the way down to 11lb.
Kind of noob when made this account so take advice with grain of salt.

Congratulations. There's more variables than body weight.

Ebonite Cyclones. Track has the Kinetics, Heat series, Tundra. Columbia has the Eruption Pro, Spoiler, Juke. Storm has the Match Ups and HyRoad series. Roto's Dare Devil series

yes, proper fit, if a ball is fitted properly u should be able to use at least 14

More to it than that.  A lot of bowlers can't use that heavy of a ball due to age or health issues.

This is a post I made elsewhere some time ago but still valid. “Having to drop below 14 lbs due to an injury, I did a fair amount of research on this. Some balls such as Radical Gurus, Motiv Trident etc are not made in weights less than 14. That said, the best explanation of the issue I got from a manufacturer was Storm. Their website posts a picture of the core used in each weight for each ball and some balls are a completely generic core and some like Alpha Crux use same shape core as 14-16. Storm explained..."This has to do with the density of the core itself. The 14-16 pound balls need the heavier weight block to create the ball. Those cores are very dense and cannot be put into the lighter balls. The lighter balls need less dense cores but the shape doesn’t match up closely to the RG and differential values so we have to find a shape along with the correct density to be able to make that ball in the lighter weights. In your question, the shape of the Catalyst weight block matches up with the RG and Differential values when at a lighter density. If the shape does not, we have to put that generic shape in to get those numbers to match up correctly. Surface composition and texture is still the #1 most influential variable in ball motion. This is kept the same for all weights. Just remember, our shapes have to match up with the limits of RG and Diff that USBC permits. This means sometimes we have to put in that generic shape to stay within this range."

Brunswick said they "use a generic core shape with a RG-differential that is close enough to the 14 to 16 pound shape so the same drilling instructions can be used." I assume Radical does the same.

Motiv said they always use the high tech core shape but modify it for the lower weight

Track, Columbia use specially modified symmetric for lighter weights”

Myself, being speed dominant, low rev, I wanted the strongest 13 lb Assym I could find and that was the Storm Sure Lock. I have had some Motivs too, don’t really look at any other makers anymore or at least, right now

Lower level equipment from manufacturers may use the same core in lighter weights, but I wouldn't necessarily call them high performance cores.  In fact, many of those cores are what they use in the lower weight versions of their high performance balls.

There is nothing wrong with a generic core.  A simple light bulb shaped core is plenty of core for a majority of bowlers.  Match your wife with a cover that will work for her.  Your PSO should be able to drill the ball in a manner to fine tune the shape she needs. 

No one puts pancake cores in place of high performance cores so I wouldn't worry too much about it.
