I am with phoenixdog on this one. I have trained both the modern way (Sport Sanda) and now recently the traditional way (Chuji and Zhongji Sanda), and I must say the differences are immense.
One thing that always comes up: injuries. Well, no. Look at MMA: if we take the average amateur MMA fighter, he isn't any more injured than your average amateur Sanda fighter.
Get a pair of MMA gloves and a teacher who knows how to apply Mantis with them (the traditional way), and you're on your way.
EDIT: I do think, however, that Mantis can be applied on lei tai or ring or whatever (because it seems phoenixdog may not that think that). But not with gloves.
