Then you haven't been paying attention. Many, if not most of the prominent WC figures have worked with different sifus, and many end up going out on their own. Since most "old school " Chinese sifus don't share students with other instructors, that means that these guys are also "break aways", except not every group is as public about it as LT. And interestingly many of LT's prominent "rebels" originally came to him only after leaving other WC sifus.
Personally I think it's perfectly normal for a person to pursue their own path eventually. In any other field of knowledge, you attend school, then college, then graduate school, maybe followed by an internship. But eventually, you are supposed to make your own mark in the world. You don't follow your college professor around as "a disciple" for your entire life! Same in sports. Athletes don't stay with the same coach or team for an entire career. Only in TMA.
Now back to the OP: ...
