Just keep doing the smaller ones flat based until your not uncomfortable anymore... do not go off an an edge please, I kringe when I see this. Those making the comments like that may have found it works for them but 99% of the time I see people do this they are off balance in the air.
approach flat, stay flat, pop flat, land flat... end of story.
huh? popping off an edge is a prereq for just about any rotation past 180. Popping off an edge shouldn't throw you off balance.
