Hey guys. I'm registered for the New Jersey NABJJF tourney and I was going over the rule book and it says cups are not permitted. Have any of you guys done an NABJJF tourney before? Is this correct? Only done NAGA and Grappler's Quest. I am not a fan of rolling without protection. Been there, done that, melted lots of ice all over the couch. Emailed them too. Just thought maybe you fellas might have some insight.
