I'm just curious if it actually does anything.
My Resurgence has lost something. I started noticing a difference in it a couple months ago but never give it much thought. I recently got a Momentum for Christmas & this ball is about 10+ boards stronger than my Resurgence. Both balls are basically drilled the same & I don't know what else could be wrong with it. I thought I'd been doing a good job of cleaning it but I guess not. I've also got a TNV, which is about 6 months older & has seen a lot more action. And it reacts as good as new.
Don't get me wrong, it still hooks & hits like crazy but it is definitely not the strongest ball in my bag anymore.
