Just for curious, I bought his "close combat training video". It is pretty much what gets taught in an introductory "bulletman" seminar. The quality of instruction is moderate. He consistently displays the bad habit of dropping his arms and blading at nearly 90 degrees.
I did get one good idea from it - always gain ground. For example, when doing a knee strike, don't step back after the knee, stomp down and keep moving into your attacker. That makes sense.
His main techniques are eye flick, ridge hand, chin jab and a "whip kick". I like the eye flick and chin jab. The ridge hand, I won't do because of the risk of injury to the fragile outside of the hand. Much better is the hammer fist. The "whip kick" is just lifting the leg - wouldn't do much damage, seems mostly for the purpose of stopping motion of the opponent. I am a much bigger fan of the stomp kick and knees to the mid section. He also uses a version of the "combat clock" 8 angles instead of 12, but the same idea. His body mechanics seem to be bladed at nearly 90 degrees and he keeps his arms at his side unless actually involved in a technique - great way to get punched in the face.
Another good idea is to plan your self defense tactics based on the direction the attack comes from rather than waiting to see what the attack is. A "first move" combination is good to work on and bring it out first automatically. My "first move" is a cross stomp kick, eye flick and then a palm strike to the face. If someone surprises me, I'll pull that out first, then start thinking about specifics.
Personally, I am not really bothered by the exaggerated claims. Everybody has a "shtick" these days and he is doing what he can to make some money in a very competitive business. I am not willing to claim I am god's gift to martial arts, so I only get $20 a month from my guys for eaching a couple classes a week at a community center. If I had less ethics, I might make more money.
