Does anyone here train at Xtreme Couture? I'm going out to Vegas for the UFC, and I was thinking about stopping by and checking out the Jiu-jitsu class out there (probably Thurs. morning the 3rd). Who generally teaches the classes? Does Robert Drysdale typically teach most of the classes? Also, from what I understand, most of the classes are no-gi, correct? I noticed on the schedule that they have a jiu-jitsu class, and a separate grappling class....what is the essential difference in the classes? Any input would be appreciated.
