No. No loss in reaction or break point shape. I like 14s better. I can throw them more games without tiring, they don't throw off my timing as much, and they carry BETTER. Yeah, I said BETTER.
I have quite a bit of hand 400+ revs and I'm definitely what most would consider a power player.
If I were to throw 15s, they wouldn't deflect enough, and I'd leave 9 pins, 4 pins, and every now and then, both at the same time.
Sure, I might kick a few more 10s, but at the cost of pain in my wrist, getting tired faster, a few 9s and 4s, a few 4-9s...I like the 14s.
I was recently considering going up to 15s, but I thought about the above mentioned things, and I think 14s work just as well, if not better, for me.
