The "slow double catch to airwrap release" is a very interesting move, leads to a lot of stuff. So far:
*Regular old airwrap release
*Buzzsaw airwrap release (Put tangled strings 180 degrees apart in buzzsaw position, let go, and IMMEDIATELY start isolating to keep looped)
*Corcscrew release (Turn your hands palm-side down, release, they will unwrap in to a corcscrew)
The whole "Stalling the poi while you get your loop halfway down the other chain" thing makes it easier, but isn't necessary. You can do it without any stalling once you have it down. Actually, an even more interesting way of getting in to it, but all together much harder, can make this a fire-friendly move. I'll explain:
Forget looping around the arm and sliding it to the chain. Why not just loop it on the chain in the first place? Spinning a wallplane weave (fountain, basically) start an airwrap halfway down your chains. If you spin clockwise like I do, open your right hand palm side up and left hand palm side down (reverse these directions if you spin counterclockwise). The poi, if done right, should plop right in to your hands. If you don't hold them too long you can do this with fire. Very quickly release in the opposite direction to un-loop, or do the corcscrew/buzzsaw business I mentioned earlier. Tricky stuff, looks much cleaner than looping, stalling and grabbing, and makes people say "...what the hell?" which is the only reason why anyone spins poi. Ever.
