Michael,
I would prefer it if someone with more Yang style experience did that.
I'm no Yang style expert, I barely know the form as it exists and is taught today. While I found Master Yang Jun's lectures fascinating and informative, I certainly would not wish to try to explain what looked like incredibly minor differences in the forms to me. It was almost always something along the lines of "And Yang Cheng Fu did it like this", at which point he would demonstrate something that looked remarkably like what we were doing to me, "but my grandfather changed it to this" and again would do something that looked pretty much exactly the same to me.
He would then do some push hands with poor Carl Meeks and show the differing intentions of each move. Those very subtle changes have some profound effects on the human body.
Could I do them both ways? Nope. I don't know that I'm doing them correctly for todays forms, so I sure can't speak about the changes from an older on to this one.
The only real one I can think of was in the "Strike Tiger" series.
IF I'm remembering correctly there was a pretty major change in footwork in that move. AND to show bad my memory is, I don't recall if it was YCF of YZD who made the change.
A glaring reason why I would rather someone who knows of what they speak talk of changes to the Yang forms.
All I clearly do recall is that now you end up in Bow Stance, whereas previously you didn't. I can remember Master Yang Jun saying something about the footwork is now clear, where as before it was not so clear.
That's all I got.
I'm definitely not your man for Yang style form changes.
