it's a comfort and weight balance thing .
all bats that are besr cert.are -3 and cant have a +15% pop over alike size woody!
you cant make it better it's illegal.
a top quality bat should give you the actual bpf rating not that it is certified . a bpf of 1.14 to 1.15 is the top end bat for speed off the barrel .
buy a comfy tough bat with a guarantee that weight balance matches your streanth . a end loaded 32 is way different than a balanced 32 are neither is right for every body . i did my paper in phy.sience on bats they are mostly a marketing rip off .
