I don't believe the dual stamp will be better. Asa only stamped bat, if I am not mistaken is made to be better than usssa. Asa went to better bats crappier balls and u trip went with better balls and worse bats! I swing a 15 og flipper and not many bats come close to it in the leagues I play in!! We use the sb12 375/44 which is too hard for the flipper but it's in real never the less!
