Hi! Kerry here… I agree with you, legs might hit the poles. That’s probably more the issue than height available if you’re at the top.
When it comes to the spin, it was never a sequence that I ever tried to do a huge spin bc I don’t love being in that knee hang for a lot longer than what you see in the tutorial videos. But try it and see if it works for you. When it comes to spinning the tail after wrapping it on the leg, for me, with it trapping both legs, it just seemed less smooth to spin after the wrap. Give it a try if you’re curious and let me know!
