You know there is nothing wrong with this type of training, but it can't be your only type of training. This website fits the stereotype perfectly. Its all marketing to the "fight club crowd" from the logo, down to the font chosen for the menu. As someone else said, "blood draws a crowd" and crowds spend lots of money on DVD's. So, it makes sense to make money off that type of crowd. Even the "only true master" and all that is just marketing, piss poor marketing in my opinion as its quite transparent, but thats just my own opinions.
The problem with the fighters is that when you start allowing this kind of fighting you loose focus of the goal. We do "bare knuckle sparring" as well but not just running around with our heads down swinging for the fences. If this is the only type of training you do you miss the opportunity to learn intricate details and skills vital to real cma fighting skill. You have to learn control not only to control your power but to control your body. In kung fu you have to have full control of your body and I didn't see that from many of the fighters on the video. To be able to redirect and yield at full speed and power takes learning it slow and understanding by feeling (both the thrower and the receiver) the principles and techniques. Only then can you really hope to be able to convert those skills into real speed fighting. Once you understand control of yourself and your opponent you can really tear up someone fighting the way some of those guys were just throwing wild punches that didn't even have the possibility of hitting the target let alone doing real damage.
This type of fighting and training has its place, but it must be done correctly and trained for correctly. We fight with no gear as well and rarely have injuries, so you might be surprised. Of course we are talking about only advanced students who not only have control of their own bodies and power but understand how to actually pull off kung fu techniques and principles and get out of them all at full speed. But that is a process that must be learned before just going in and just swinging out. We just had our annual titling where we went and had to fight 20 other students all back to back. No gear, etc. However only one person went to the E.R. and that was for a separated shoulder he really did to himself. So its valid, just has to be done properly and with the right intent.
Ok, off my soapbox now...sorry....
