It isn't the purist shape though
Ask b3 who invented that shape there say something different they do not claim it either
Tom is this concrete, or will a whole lot of begging persuade them to tilt slightly more to the old shape?
I think the first bat I had seen with offset edges was a Special profile from Laver, and the person said it was from 2008. Might have actually been your PB Dave. I'm not sure who invented it, but the first person I heard about the thinking behind it was Andy at SAF!
