One problem I often have with headtossing, is that at 100 DMT, I often break my wrist and having to resort to crappy, weak throws that don't look good.
So I set the DMT to 400
Here's a way to rip off your head at 400 DMT.
Hold all
Extend both pecs
Contract both elbows
Advance 10 frames
Contract both pecs
Extend both wrists
Grab both hands
Raise both shoulders
Advance 30 frames
Extend neck
Advance 10 frames
Extend both elbows
Contact both wrists
Space til done.
If you are having trouble ungrabbing, hover over your wrist and press 'L' to ungrab.
