RamK...A Bubba training dummy or something similar would work, but it's really about mental preparation. When I trained in BJJ, we were also taught Vale Tudo. There are some techiques and sweeps that I wouldn't do, because they were dangerous if striking or headbutts were allowed. My reason for taking BJJ was for self defense.
EctoCooler...thanks, but I'm aware of the law in CA. In CA it's very difficult/almost impossible to get a concealed weapons permit (CCW) in CA. I do not own my own dojo and even if I did, I don't think that would help. You have to know someone or work for a high profile person who can get a Chief of Police to sign off on it. I may have to move to Arizona, LOL.
