This may have already been stated... I don't know the history of the chain forms but I was under the impression that this weapon is much like other weapons that were borrowed from other styles, atleast in Hung Gar. I wonder if there really a souther chain whip or if it is just variations on other outside influences?
YC Wong Sifu is sometimes associated with the chain whips. He seems to have a high level of proficiency with the weapon. So I guess this form is as good as any others. Here is a short scene at the end of this clip

I've only just discovered my error, and I'm going to have to replay whole sections of my life through my mind to see what confusions I may have caused or fallen foul of.
