Any one ever heard of sark securities. I have finally convinced my dept to send me to dt school. Would really like to go to Tony Blauers Spear course. I'm a cop in Pa, and now these sark guys are putting on a class. My Lt got wind of it and asked what I thought about them. Went to their website and I am not feeling it, too commercial. Tried searching for reviews, but couldn't find anything. I have been boxing and doing bjj for about a year and a half now, don't want to waste my time and depts money. I went to a state police course and it was a joke.
