Each one has its own gimmick. You see all the new bats during the College World Series and that's the new line for the following (prep) season. You've got the top of the line all the way down to the ones that supposedly aren't as good. What's the difference? Price? Nobody seems to know the answers. The companies say there are differences, but I don't think I see the ball going any farther or coming off the bat any faster.
