Are you going to do any modifications to the wing retention method? The SFGs are going to try to remove the wing from the fuse during large yaw angles. I would also think the stock threaded hooks in the wing root are not up to the loads involved as well. Food for thought.....
I think the hooks are fine it's what you use to keeep the hooks together that may be the issue. I've always used a fresh rubber band looped around a couple of times but consider a zip tie.

I couldn't resist
