Does anyone have access to the equipment used to performance test bats? I would LOVE for someone to get a couple of marquee name bats, test them right out of the wrapper, then have them rolled, and retested to see if there is any performance improvement. I would guess any improvement would be minimal, and you are probably (not sure how to test this) shortening the life of the bat.
Couple of things. First, dd was a freshman in HS then and is now a junior in college. So, this was a few years ago. The changes, as has already been asserted, have now been made to lessen the difference with composite bats. Also, I have not seen the equipment used to test bats but do know that in the NCAA Regional, ... they test bats every day. DD had her bat thrown out last year during the second day of regional but her backup bat was good. She did ok with back up bat. DD had back up bat thrown out 3rd day of Regional. ????????? Makes a person wonder how her first bat passed first day and not second and how her second day bat passed second day and not 3rd. In fact, 8 bats of her team didn't pass the 3rd day that had passed for 2 days.
If the guy was bragging about it then takes off running with it I believe we are beyond assumption.
Pretty good read.
Do Advanced Break-in Techniques Really Work?
This article was written in July 2009. Would love to see an article with similar testing on 2014 bats.
The friend that had the bat is a local business owner a good guy and friend of mine. He had the bat still in the box and he advised his dad purchased the bat and paid the distributer to roll the bat; a common practice according to him. The box was from a well known distributer. I told him what I thought were the current rules on rolled bats and he assured me I was wrong. In all my years of going to games I never saw a vendor rolling bats in the open, but he advised it is a common practice. His daughter plays NSA, USSSA and middle school ball.
