I started under a Carlson Gracie school. Pretty tough. Vale Tudo based. Make it hurt if you can. Take a heel hook if you see it. That kind of place. It was close to a nice university, so half of the students were average sized med-students and pharmacists. Not just the "where do I sign up for dat UFC" types. Even than, everyone was expected to roll with everyone, and if you got beat you got beat. If you got injured you got injured. Our gym had an atmosphere of "no pussies allowed" so no one really complained about things. They just said "I'll see you next week" and never showed up again. Back than there weren't many places to train in Houston, and this was my first "proper" introduction to BJJ, so I thought this was what BJJ was supposed to be. If someone asked you to roll, you said "yes". The 125 lbers rolled with the 280 lbers (and often won) and the dainty girls would roll with the juice head guys. Countless times I would roll with people that not only did I not feel like sparring with, but with people I had a very good reason to deny, but I simply didn't. I carry that mentality today. Now I train in Japan where at 155 I am a pretty big guy. A lot of people turn me down for rolls. Not just that, but I go to English speaking sessions where one guy will say, sorry I don't want to roll with you, you are just too big *at 40 pounds heavier* this is COMPLETELY foreign to me. The Brazilians I have trained with will say the same thing. ie: "I can't roll with you. You are too heavy." I've always felt that you can't have complete jiu jitsu unless you spar with everytype of person. A small guy who knows what they are doing will present very different problems to a big guy who knows what they are doing, and even if a spazz is annoying, I don't think you can be well rounded if you know how to roll against a spazz. Just my thoughts. Do you turn down offers to roll? Why? How often?
