I suppose that needs clarification--I'm not talking SD, here. My SD teacher also runs a kuntao-silat club on a monthly basis, with periodic extra training during the month. We do a lot of bladed work. I think I saw Sean at one of the first meetings, once, where we worked on the seven seeds of Harimau. I can't recall, though. I'd prefer to keep immediate names/lineages out of it (some is Suwanda, some is De Thouars), since I don't like dropping names in this trainwreck of a thread where everything comes under attack. I'm sure Sean would agree that much of Silat and kuntao is like kung fu, and much is not.
As for "knowing" techniques. A good cap requires some dextrous skill, and there's no capping in Tang Lang Quan. I know it from WM STP and Cha Chui, but I had just learned those forms. IT was my my 1st degree black belt exam (testing with all brown belt material), I think. PRobably 5 years ago. I cap quite a bit, now. It's a nice attack/setup, although you occasionally poke someone in the eye.
