There's an interesting form called si lu beng da. I wonder if it's part of Dr. Yang's long fist curriculum?
Here is Han Qing-tan doing an early verison of the form:

One reason this form is interesting is that it was originally a praying mantis form. But Han Qing-tan reworked it into a long fist form by adding long fist hand movements and postures. He did this because he was famous for his kicks, but he didn't have a form that highlighted those kicks. Si lu beng da as taught by mantis people has lots of great kicks so Han reworked it.
HERE is a nice version of what it wound up as.
Thing is, he was still unhappy with the form so he eventually created his own kicking form: yanqing tui. This is, of course, completelt long fist in character because Han built it from scratch.
Here's a clip of my shixiong (elder brother) doing the form:

Is yanqingtui part of Dr. Yang's curriculum as well?
