@Six Sixes Cricket is right, not many people outside of this forum would know the allowed max width of a cricket bat, let alone really care.
I've said it before and some on here wouldn't want to hear it, but we're all responsible for this in some way. It's always (90-95% of the time at least) about 'specs' and something has to give.
@KW9221 states abv that he'd take a 36mm/37mm edge at full width over big edges and narrower. This is the issue here. 37mm edges aren't considered big anymore???!! Good luck being a batmaker and making consistently full bars with 38mm edges, high spines etc at lighter weights.
Until smaller edges are accepted and we all stop talking like bats have to be fill the gauge, then this sort of thing is what batmakers will do to sell bats I'm afraid.
