Does anyone mix in combat jiu jitsu at their schools? If so, is it a special class or do students just opt out? This is directed more towards BJJ academies and not MMA academies.
I did a combat BJJ match a while back and one of my students did a few. For this reason with that specific person we added the slaps into the rolling. This causes a lot of chatter in the gym and will be extremely off putting for many. For this reason I had to make sure everyone at the gym knew what we were doing, why, and more importantly that this will not be occuring randomly in rolls with them.
If I were to have a constant presence of combat BJJ, I personally would opt for separate classes. Unless you want the whole culture of your gym to be the type of people that enjoy the strikes.
I think I'd opt in if it was available, but I can imagine that it would not be something a lot of the gym would be comfortable with. Especially as I imagine quite a lot of people choose BJJ out of concerns for CTE.
