In the interest of sparing my wrists in particular, I've further reduced my template to:
(A) L-sits and back lever progressions
(B) planche and front lever progressions
Workouts are preceded by handstand work and followed maybe with a few pistols. Not focusing on the lower body as I also get in some sprinting, jumping and stair climbing.
Spoke with a couple of gymnastics coaches who assured me that my bent-arm strength would not suffer in the interim.
