This goes to the whole "rolled bat" discussion that has been hashed here many times. Please, lets not revisit whether that is legal or not.
This biggest thing to remember is the bats, starting in 2012, will have to meet the new BBCOR rating.
I have to think that this year and next, the only thing different in manufactures bats from previous years will be the paint.
"During the 2009 Division I Baseball Championship, composite bats were selected for ball exit speed ratio (BESR) certification tests. Of the 25 bats tested, 20 failed the official BESR test for current NCAA performance levels. Because all bat designs must pass that test before mass production, the results indicated that the performance of such bats changed thereafter, most likely due to repeated, normal use or intentional alteration.
In the meantime, the NCAA plans to conduct additional testing that will provide the baseball rules committee another opportunity for review. Additionally, the committee is open to providing an opportunity for companies to prove that their bats would meet current NCAA standards regardless of use or tampering.
As for beyond the upcoming season, the baseball research panel is recommending that an Accelerated Break-In (ABI) process be added to the certification process under the new Ball-Bat Coefficient of Restitution (BBCOR) standard to help address the issue of improved performance and further the goal of having all bats in NCAA play remain under the NCAA limit through the life of the bat.
The BBCOR is a method designed to measure the performance of the bat. The ABI is designed to replicate repeated use or intentional alteration of the bat. This process has been used with some success in the certification process for softball bats."
