1 and 4 seem to have the thighs to squeeze out a solid scissor...i'll go with 1
Sorry, NYOllie, but judging by their abs I would say #1's thigh size may be due more fat than muscle. #4's are all muscle. In fact, #1 has the worst abs of all of them. Too bad #3 and #5 have tights on so you can't really see their quads muscle definition.
