They keep changing it. The last thing i saw was that they're going to do like asa with the 100 mph bats. At some point, you can only make new stamp bats going forward, and the old will be legal indefinitely. Which means if they don't break or fail fast enough they'll decide to ban them down the road.The Easton Slowpitch Book of face page just reposted a usssa/gsl post, that states all thumbprint stamps, will be legal indefinitely
What they haven't cleared up is whether they'll get to be legal with their old compression standard or not. If They have to be over 240 then they'll be legal for 50 swings and then who gives a ****?
