Hello Ken:

I liked Sean's answer over at Budoseek too grin

Unfortunately my practice does not contain any of the post WW2 "additives" (sic. Japanese). But from the discussions, writings I've read on the subject primarily support the beginning version and a more difficult variation idea.

Having both versions IMHO is completely redundant. Why reinvent the wheel??? But perhaps the versions are sufficently unique couldnt say... myself am quite content with Wansu, Neihanchi, Kusanku with nothing extra added or reinvented later on. Its tough enough with them alone....

Wish I could help...
