well 5 low,...
i guess i would try the same as robin does, since i try to do this with 4.
another way would be the 3d armtall and trapez on the other side with throwing up 2 and then opening.
but i don't see a point in trying 5 low nowadays, i think people will have to get WAY better at 4 low (tricks, accs and correction) before they will be able to do a proper 5 low control. (sure im convinced someone will hold a pattern for ~ 100 catches in the near future) i am speaking of controlling 5 low with correction and stuff.
