We have the rule that a spot is allowed to touch the foot, the ankle, the bases arms but can't have both hands under the foot.
To me, that isn't true coed stunting. If i have a base and a flyer, and they are doing a rewind, high to high tic toc or other elite stunts it is harder than having a base, a flyer and a "spot" who can help with the catch at toes, ankle, bases wrist etc.
It shouldn't be worth the same. But that's just my view :)
I'm sure there are many coed teams that could do great stunt sequences with real coed stunts, and they would if needed to max. difficulty.
