^^^do you notice a difference from the '13 to the '14 to the '15? Aside from differences due to hit count? I LOVED my '14. Took a few hundred hits to really open up, but was good out of the wrapper.
M13 was hot out of wrapper, but had some fragile issues/compression fail, very quick.. .but bat is hot as hell...
M14, much stiffer out of wrapper then the 13, but still performed well... but nothing like the 13 out of wrapper... fixed durability issues also, bats lasted longer...but eventually, they get about the same performance, just takes a while...
M15, a tweener - not as hot out of wrapper as the 13, but also hotter then the 14 Out of Wrapper.. but they kept the durability... and eventually, its just like the 13 for performance... also, after the first batch (oh did I just Batch this bat?!?!?!), they removed, Designed for Women from the bat.... I guess some men thought it gave them limp **** or something... lol
overall, here is my final take.... 13 give it 300 cuts and it will piss fire but fail compression - 14 give it 700 cuts and it be like a 300 cut M13..... The 15, give it 450 cuts and it will piss fire, but again, fail compression....
3 awesome bats... just need to be careful if you get comp tested by your league or tourneys....
