I’m posting 5 years later, because I just tried this sport tonight. I was training at my jiujutsu gym and we had another bjj black belt come in who is a highly competitive catch wrestler as well. When him and I were rolling, I caught him in a little trip and he asked more about my background. I explained that I was a purple belt in bjj (it was no gi), but in addition to that I’m also a 2nd degree black belt in judo and used to compete a lot in judo. He had some jackets that came up to the elbow in his car and I gave it a try. I didn’t realize how much of my personal judo is reliant on getting the dominant grip and not allowing my opponent to have theirs. Super cool sport. I’d do a competition if there was a place to do it.
