Fingerspins helps a lot for antispin mouvments, if you want to keep the figure, pentagon, exagon, whatever.. in front of you. But I'm sur Simian can find a contortion solution
anyway, for doubles, making a penta or exagon "One beat shifted" , you need to turn on your self even with fingerspins to finish the whole cycle.
otherwise, you might cut one of your arm ...

Or ask Simian

I'm actually not really interested by butterfly antispin... you need a double transfert for that I guess.
It's really better when you can synchronise it with someone else: one staff each (or two but parallal shited

), so you take more visual space, it's easyer to do and it looks better. for me

PS : Shay... I just love your spin !! you're soooo good

never see such clean double antispin. I try to learn how to read english ... do you?
