I was wondering if you guys could check out the bios of the two main instructors for this MMA Gym. Do they seem fit for taking me to a competitive level? They have their Brazilian Jiu-Jitsu training under "Master Ricardo Murgel, 8th Dan" I have never heard of him so I am wondering of the quality of jiu-jitsu training.
