don't even consider until you have cork 7s/9s locked. Assuming you do, I'm sure you know that point in a cork 7 at about 540 where you spot your landing and start to open up. At this point, do NOT do either of those things.
Basically, just throw it like a regular cork 7 but keep your legs tucked up or holding your grab and continue to have your head and shoulders committed to the rotation.
