Wings go just behind the trailing edge of side fins so water releases right behind the fin. That’s where my experience with wings begins and ends, ha.
I think, though, that a sharper bump, like a straight angle cut v. a soft bump (besides being difficult to glass) would give you a tighter turning radius, because you’re reducing tail area and releasing water from the board faster.
What are the other dims on the board? How’d the first one come out?
