Each of the traditional lineages and their off-shoot branches has strengths and weaknesses.
Within the "WT" branches (coming from Leung Ting) you see that too. Sifu Leung had legit skills within the confines of what WC/WT
is: a short bridge (close range) stand-up, striking art. And in the early years (1980s) that I trained with LT, he was more generous about sharing his knowledge.
Later on, politics and money soured our relationship some, and my life situation changed. I married, started a family and career, so I couldn't really continue as before and left off training WT.
About 15 years later I gave it a second go and ended up training with my old si-dai who had reached "master" or "practition" rank in the interim and was running LT's organization in the US at the time. On the positive side, he had trained both directly both under GM LT here in the States and also for some years with the EWTO in Germany, including time directly with GM Keith Kernspect. On the negative side, shortly after I started training with this man, he broke with LT so both he and his group (including me) got "excommunicated".
Now I'm kinda independent ...of everybody. I still travel about 1,000 miles to train with my si-dai about once a year, but he is rigidly traditional and authoritarian in his teaching, and I like to explore ideas and try different things. So we don't totally see eye to eye. I'm still happy to learn from him, but he's no longer so happy to share stuff with me since I'm independent and don't run a school branch for him anymore. Funny how history repeats itself, eh?
So what about WT? In my experience, LT was very good, and his
soft and flexible interpretation of the WC/WT system was fascinating and effective. I feel that it was among the best WC that I encountered.
On the other hand, his claims that his WT is a totally "complete" art didn't hold water even back in the 80s. And now with over three decades of MMA as a "proving ground"...such claims are patently absurd. Certainly, WT has merits, but to be a complete system that could be applied successfully in open competition, of course you need a good grappling background as well as long range punching and kicking skills. For most young, athletic people who "want to fight" a good MMA gym would get you to that goal faster ...if that's what you want.
On the other hand, for an older guy who does TMA for recreation and ...possibly might use it for self-defense some day, My WT and Escrima, plus the experience of having been a wrestler in my youth ...well that suits me fine.
