You guys aren't really getting it.
In the last 20 years, composite bat standards have both;
A. come in place
B. evolved
C. essentially capped legal abilities of a bat.
Back in the day a difference between 300-and 30,000 swings to get a bat super hot was a big deal. Now they all come out ready to roll.
Back in the day there really was no broken in standard. If it got into the game, she was gtg. Now, that 220 line creeps up after a few hours of BP.
Back in the day there was not compression testing, if your bat didnt have a crack or wasn't suspect she was fine
Back in the day you could shave a bat and get years of use, people cared about long term durability far more, and it enabled cheating far more, hence more feedback needed.
They make bats specifically for a ball spec now.
Literally all the bats are gonna be good now, there is so minimal performance differences its unreal. its all about feel.
Your weight
Your load
Your stiffness

There really is not a need for bat reviews anymore. Its more about figuring out what fits your swing spec wise, and sticking to that.
