My fastpitch team has been using Combats for a few years now and they are the best bats out there.  Some of the girls have other brands, but the combats are the bats I buy as team bats.   I've got 5 of them in the team rotation and they are well-broken in, all scuffed up and balls just launch off of them.  When we need a big inning we "rattle the bats" in the bat rack and the bats wake up.  They take a beating and just seem to get hotter and hotter.
