Well ya know my fave type of headscissors is the reverse standing headscissors. I call it my Ami Clamp lol. I know clever name right?? I love it though cause ya get them on their knees in front of ya and bend them backwards then lock in ya scissors. Puts pressure on the back, its hard to get out of, ya can control their arms easily from there and makes it super hard to breathe and lets ya really work their head hard. Course its totally patented so if ya use it ya gotta send me $50 LOL
