a little risky, but great to surprise others:
use the animation to buffer the first 360 and release the other as you will, partitioned or not
canceling the animation fast enough is a little tricky, think as doing reversals
whiff lariat/defended lariat - gigas
whiff short meat squasher - gigas (j+hk, c+mp, strong/fierce clap gives perfect distance to whiff and cancel to gigas)
whiff throw - gigas (PERFECT for missed/guarded shoryuken and similar)
whiff uoh - gigas
using partitioned gigas, there is a very nice enemy reset setup in the corner
Ultra throw - j+hk/j+mk/j+mp (first 360) - walk a little - gigas
Ultra throw - s+mp/s+lk/c+mp(first 360) - walk a little - gigas
Ultra throw - body splash(jump d+hp) - whiff jab palm or c+lk - immediately gigas
for not giving in too much, after reset, you can mix with double/triple palm combo, backbreaker or meat squasher/dash - moonsault press
hope it helps
