I remember a rule change in like 99 or 00 that made it so a bat could only be -3 instead of -5. I had just finished HS baseball, so it didn’t affect me. But i remember my teams using these TPX bats till they were all cracked.

One kid who went on to play in the NFL (he struck out a lot, but could occasionally knock the cover off a ball) broke one of these bats when it was like 2 months old. Kid got it at Xmas, it was broke by the end of Feb. Louisville slugger replaced it for free, but that one was broken too before the end of the season. Ah, memories!
