Ok, I'm going to give you some lists of trampoline skills. Start at the top of each list, read down until you see a skill you DO NOT already have down perfectly, confidently, consistently on a trampoline. Basically, tell me what's the first skill on each list that you would NOT be able to nail cleanly on the first try.
BACKWARDS SALTOS, LATE TWISTING:
-Back drop
-Back drop pullover (ie flip backwards from back drop) to hands and knees
-Back drop pullover to front drop
-3/4 back tuck from feet to hands/knees
-3/4 back tuck from feet to front drop
-3/4 back layout from feet to front drop
-3/4 back layout from feet to front drop, 1/2 turn to feet
-Back layout from feet to feet with LATE 1/2 turn (see the trampoline first, then turn)
ARABIANS:
-Back drop
-Airplane (take off backwards like a back drop, but 1/2 turn before landing so you end up in front drop)
-Arabian 3/4 to back drop
-Arabian tucked to feet
-Arabian piked to feet
FORWARD SALTOS, TWISTING:
-Controlled bounce on hands and knees
-Hands and knees, front drop, return to hands and knees
-Seat drop, hands and knees, 3/4 front to back drop
-From feet, 3/4 front to back drop
-Front 3/4 layout to flatback (can use a mat throw-in for this, or do it off the end of a tumbletrak)
-Front 3/4 pike-open to flatback
-Front pike-open to feet, with arms wide in the pike phase
-Front pike-open-1/2 to feet
Let me know on all 3 of those lists how far down you get before you see something you don't think you could nail cleanly on the first try on a trampoline. I'll use those as a starting point for progressions to suggest.
Once you have a correct back late 1/2, arabian, and front 1/2, you can do anything up to about 1.5 twists per flip without ever losing sight of the ground.
