Do it! My 12U son is swinging the 32/24 and loves it. He told me that he thought the Catalyst has a little more pop, but they also break a lot more and he was getting tired of waiting for replacements so he decided to switch. Good luck!
I think its the best bat on the market. my 14U son swings the -3 and loves it. My younger, 12U uses the -8 red we handed down to him. We switched from Stealth's to Demarini's last year after seeing others use it. The ball just jumps off the bat. the Voodoo isn't a bad choice either.
