Yes, I meant to say -- it's about 50% tumbling and 50% partner acro, which is PERFECT for me. So far we've always worked on handstands and front handsprings; we've always done two-highs, which means one person standing on another person's shoulders; we've always done some 3-person acro configuration as well.

Back flip, yeah, way scary. I'll content myself with a back walkover -- if I can ever do that without a spot, it's enough, I'll be delighted.
