Thanks for the reply, and explanation. Wu Dip Ma is a tough one and takes a lot of practice. What's interesting is how often it appears in the forms. Hardly at all actually.
Interesting yong fa for it though but no good at all if not trained.
As for the others (sei ping ma (riding horse), dun san ma (hill climbing) and gwai ma (kneeling)) I have to disagree unless you can explain specifically what's done wrong in those 3 stances.
I was thinking it was the turned in toe being poor alignment but guess I was wrong. All I ever hear is that the WL leg alignment is off on their stances. Maybe someone can explain how Wah Lum riding horse or hill climbing horse differs from other styles.
I've also attached a photo of my representation of die bok ma with double broadswords for anyone to correct if I'm not doing it right. But then I'm not exactly the best representation of Wah Lum since are many more out there much better than myself.
