Prolly a good test would be a pose applied to some radical figures, like say, V3, Freak, Heavies, power pixie, Daz Troll, Nebras, Koshini2, and maybe Sal a Manda.

That's a pretty radical comparison group, and in theory, each should be able to take the universal poses, because they are all bipeds.

Way too many people take way too many things way too seriously.
