First off I guess I get confused over whether there is any difference between no-gi Brazilian jiu jitsu and submission wresteling    The only difference I can think of is that sometimes in rare circumstances wrestlers are able to out point other brazilian jiu jitsu trained people in a competition setting. Some tournaments that call them self submission wresteling tend to cater more towards wrestlers turned grappelers while gi based federations will hold no-gi tournaments that draw people trained initially in gi. In fact pretty much everyone worth anything in competition started out in gi and then transitioned over once they developed their base. Both are equally important parts of the art.    NAGA (north american grappeling association) puts on tournaments across the nation. It's a great lower tier tournament for people wanting tournament experience.    For really top level competition the holy grail of no-gi jiu jitsu is ADCC which is an inivitation only grappeling tournament of the best no gi jiu jitsu practictioners in the world.    IBJFF which holds the most prestigious gi grappeling tournaments also holds world championships in no-gi that are also extremely prestigious to win in.    I've been rolling for about a year now and recently got stomped in my first NAGA competition by wrestlers that used positional control to out point me while I tried for submissions in the gi and no gi division. It was a great experience and showed me a lot of things I can work on to really fill out my game.
