I was told by the man himself, that the only change it the paint. Same with Juggy, Mercy, and CL22. But I keep reading on FB...how much better and hotter the new line. Its soo funny to me.
I have personally hit both of the bats side by side my 2014 future has over 1000 swings on it. we were in a cage but i will have to say that the 2015 felt way hotter and had a little different feel to it. but in my opinion its not a repaint.
What is the break in time like for the 15? Probably be swinging a mix of 44's and 52's inside until it gets warm enough here.
