I agree with Ohio Wave's ?post. It may not matter, if you read the new testing procedure that goes into effect July 1. Many bats will probably fail this new test. ?Currently I agree with the old RT bats, but with the new rules banning bats that rattle and this testing. I'm not sure what will pass. RT's if not handled correctly tend to develope a rattle as the fibers break loose. I'm not sure if anyone is reading the bat information and what happens when they go use the bat and then leave it in the car during cold weather.
