When you guys start filming another season, I would recommend trying out the CDT system. It is a non-lethal self defense system that many law enforcement and security personnel use. It is still fairly new. Then if you want to go lethal, you can try out LRT (last resort tactics). They show you some crazy moves used by military and special forces. Like killing a person with a towel or rolled up magazine. They also do alot of gun/weapons disarms. The craziest part is when they knock you out and make you get up and fight 3 guys right after you regain consciousness. Here is a site you can check it out at: http://www.cdt-training.com/CDT%20courses%204%20Security.html
