Yeah, it does suck that they've throw so many rules in there. My old instructor teaches shootwrestling and when the tournies first started being run, everything was legal! Over the years, he's had ton's of Relson Gracie students come down and their instructor has actually started helping out with the competition. I honestly believe that the rules change is due to a HEAVY influence from those BJJ schools coming down. Over the years where heel hooks, toe holds and neck cranks were allowed; there was never a single injury from these moves yet they still banned them? DEFINATELY HEAVY INFLUENCE FROM BJJ!!
I've competed and won at the last two but it really did limit my arsenal. At this same tournament, there was a guy that whined and complained because he was crossfaced too hard and didn't like having an elbow digging into his face. He whined to the referee after I tapped him with a shinlock saying that I was toe holding him. I actually had to sit the ref on the ground and show him what I did in order to no get DQed. I did have to make sure that I was doing a "shinlock" and not a toe hold before actually applying the move which isn't a good thing to have to do when grappling.
It's sad to see such a good tournament go down the tubes. You'll even probably see on the UG in the next few days the Relson instructor coming on saying that their team won the "team trophy". What he won't tell you is that out of about 15 schools, 9 of them are Gracie schools and they all pool their points together to win the trophy. So everyone can come in last place and they would still win the team trophy. One of their students told me before that the instructor wanted him to intentionally sand bag(even though he's a purple belt) by competing in the intermediate just to win trophies.
It's very sad that instructors sink that low just for trophies. That's why I'm a Ronin I guess :)
