Could the girl in a handstand technically be the flyer of the two "bases" holding her in the handstand? Then this would be like a pyramid fly over?
If she had her hands off of the ground yes. If you touch the ground at all though you are not a flier. Would've been a lot harder then too lol. For the record I wouldn'tind the wording of the rule changed to bases can not be in a back bend. I think the intent of the rule is to prevent people from literally basing while in a handstand and the obvious safety part of the backbend.
