Sorry, but I find it hard to believe you cant get a triangle, or some variation thereof on the guy. Maybe the choke wouldnt be textbook, but surely you can fit a head and an arm between your legs. I never said the triangle would be the best option, and clearly it isnt. But in my experience someone with good technique can triangle pretty much anyone unless youre talking serious extremes. Im not being rude, and maybe you really cant nail the guy for whatever reason. But i think that puts you in the minority when it comes to the triangle. Its a choke perfectly designed for small guys to use on big guys, Ive never had a problem with it and im 5'8".
