Hua Lin excelant points . the on going R&D of a MAist lead all to explore other things to ? what they are doing and to evole as new insight is gained. one of the areas that I find myself going is the greater intergration of internal training into the mix that I teach , than what was presented to me. As wellas a more practical hands on useage , althoe that may just have been WL's evolution to it's presant day forms oriented training, I rember that it was not always that way. This not to say that IMO it has always beem very froms oriented, may be to much so IMO.
