I'm scared of doing those spins. The only spins that don't scare me are backspins, buttspins, windmills, (you might call that a spin if you like) and handglides.
If I'm really pumped up I can backspin on a gym floor and get about maybe 8-10 rotations. The problem with my backspins is that I eventually start rocking between my shoulder blades and then fall over when I still have enough momentum for a few more spins.
I've tride backspins from handglide. I get the same amount of momentum, but I also get too much rolling momentum. And drop coindrops, because my body is all wierd. I kick into my backspins and get 8-10 *insert imaginary smiley:OMG Bboy Masochist can do backspins without coindrops:*
