I have many of Chris’s DVDs unfortunately and I think he is overpriced. I have his mercenary combatives and the new SSDF course. Also overpriced. There is a lot of similarity with the SDC system but the system in my opinion is better and more functional and also with his claim of just watching his SSDF tapes is all you need to do to ingrain it in you is b.s. In one DVD he even admits that his so-called by the numbers system he “invented” a few years will not really work against a stick or club attack. He does admit when it comes down to it a club or a bat is a club or a bat. The “number” idea goes out the door. You can gain some stuff from the “Captain” but I would stick with Damian’s material as like I said I have a lot of Chri’s stuff and I would give it back if I could.
