Lefty-hitrak,
I have to disagree. I went to 15 lb balls back in 1997 because of a hip injury. I can still rip the cover off a 15 lb ball. It does not ever deflect.
BUT with a 16 lb ball, like LuckyLefty said, you (actually, I) get more strikes, PLUS, it helps my timing. I can too easily get too muscular with a 15 lb-er. I much less likely to get that way with a 16 lb-er, PLUS, I can last longer later into the night. So, sadly, I use 15 lb balls, about 97-99% of the time.
