Downed Guard in MMA

Looking for information on how to play the :downed guard" (aka Stage 5, purgatory) in MMA. Basically when you're on your back and your opponent is standing over you. What do you guys like to do? GJJ basic sickle and tripod sweeps are there, but they create more of a scramble then a sweep without a gi on. Any advice or techniques would be appreciated.

Just a WB, but if you're hitting a sickle couldn't you transition to ashi from there? Then again, I know Eddiehas said he's gunshy about leglock game in MMA...
