It's my go to for guys with giant necks/shoulders. I feel like using my whole body to jam their shoulder into their neck is usually easier than fighting for a rear naked or north south plus I feel it catches people off guard.
Been using it a lot. Herzog has a video that helps with the finish. You really have to crawl your bottom arm through all the way to get a proper choke. It's a great move to pair with the darce as someone already said.
