Garyr, I've seen that e-book or series of e-books before and I've probably downloaded it/them to my computer at home. I have skimmed over it, but there was just too much in there for me to really start trying to figure it out. Perhaps after I'm done learning the form our teacher is doing with us now, I'll have enough knowledge to get something out of looking at the Yang Lu Chaun form.
disciple, I'm pretty sure you're correct about the 48 posture combined form. Since it includes moves from other styles, e.g. Chen which is noted for having explosive movements, it would have some hard movements in it. I don't think there are a lot of hard moves, but there should be a few, maybe half a dozen or so? Something like that I think.
Rob_Broad, I know what you mean about the schools. This is one of the things I was concerned with when I was looking around for classes being given in my area. I heard too much about how most schools don't know or at least don't teach tai chi with/from the martial arts standpoint. I was afraid that where ever I went it would be treated as simply a health exercise and I knew it was more than that. That's why I'm glad to be learning it from our teacher who started us off with long fist. He has shown us some fighting applications of tai chi moves to help us understand them, so he clearly knows about the martial arts aspect of it. I'm glad that I'm learning it now and from someone who knows the martial aspects of it.
