when cutting the wings, try to avoid sharp 90-deg cuts/angles. the stress will be focussed on the intersection. if you have a chamfer/taper, then you will distribute stress around that point. especially useful at the back of the wing. my $0.02.
also, the wing plays a big part during jumps. the ability to trim the rear edge of the wing is a useful tuning tool. unfortunately i don't think the ofna wing allows you to do that although admitedly, it is damn beefy. but you might end up breaking wing mounts instead
