Rubber pencil

i have been comfortable with cross ankle/knee realease and bow and arrow for some time and can do bow n arrow w 1 hand, but cant seem to figure out how to get into rubber pencil (like bow and arrow except foot is no longer hooked around pole and both legs are off pole w legs bent at knees ..sort of like doing a back bend on the pole) i cant seem to find my balance or a way to unhook foot wo falling off the pole. any tips? 🌸 ☀️
