I should not have said "vast experience" but rather lots of experience. San Da and Sanshou by direct translation means the same thing "Free fighting" or free style or just free sparing. So if you want to argue about how long San Da or Sanshou had been around, well it is certainly as old as the language itself. As for my experience, I studied Chinese martial arts since I was 8 yrs old and I am now 42. As for San Da and Sanshou, I was trained in something similar since I was 12. I love my Chinese martial arts and i still practise it regularly and I also find myself using the free sparring techniques I learnt in Chinese MA in my Muaythai training. I have never mentioned that San Da and Sanshou is useless, however all I am saying is that Sanshou as a ring sport is a recent creation. All this arguments are absolutely useless as all martial arts has their own application and methods. Given more time and experience I have no doubt that San da and Sanshou will flourish against Muaythai and right now is just the beginning. Your point is correct, but I am not blaming the style but just the evolution. All I am saying is the style of fighting is just suitable for other application not necessarily ring fighting. Colin brought up a good point about the elbows.
