Draw out a 2mm radius leading edge. There probably wasn't a model out there that would have passed the rule if enforced. The Contest Board is a very funny committee to deal with.
I took a hole punch to a business card...7.5mm diameter and it matched my Prestige stab. The wing looked like about 10mm diameter (5mm radius) at the tip. So the Prestige would have passed (and probably the Bravo as well.) Happy to hear we are able amuse you!
