Anytime I hear of Sub-only super fights it pumps me up bigtime. It's awesome to see more and more tournaments ad the sub-only format. Big ups to the heads of World Jiu Jitsu Expo for producing such epic match ups. The Miyao/Fitch match in particular was extraordinary :) 
Renzo is working really hard to make this event grow. There are a lot of improvements to be made but it is already an awesome experience. Who would have thought an event like this would have happened?
I didn't know this was Renzo's event. Way cool :-)
