Excellent username, and good for sweeps and/or setups, but as an actual submission, you are just trying to bully the other guy's arm, and so, hard to really pull off in competition (BJJ or MMA), where you are fighting guys who are in shape and generally pretty strong. Something like the twister is the opposite. You could probably submit Hafthor Bjornsson (or Brian Shaw) that way - it's a pure finest neck crank - but man, the set up is insanely hard.
