Let's not forget that BL's relationship with Yip Man was strained, and he really never learned the entire system, and Yip Man was quite old at the time, and Bruce didn't really train very directly under him, and, and.......so I don't see this as meaning that he met with a superior system, just superior fighters. Oh, and BTW, have you ever seen old pics of Gin Foon Mark? The man was buff to say the least. Sifu Norman Chin is also pretty muscular. no wonder they threw him around like a rag doll.(from what I've heard) I don't think that there is one superior system, just superior fighters. These systems all were developed about the same time, during life and death struggles. If there was a superior style, the others would have gone by the wayside. It would be pretty stupid to continue doing a system, stubbornly clinging to it when a better method is developed. These systems are simply specializations born from each individual founder's preference for specifc techniques and concepts. In other words, "It's all good!"
