Those mentioned in the thread already are the only ones I can think of right off hand.
Most that are discussed are variations of LavaTubes, VMax, ZMax, etc. I'm sure I'm

You can find all kinds of talk about those things and more on these threads:
APV Discussion
Grab a pot of coffee and pack a lunch cuz there's enough there to keep you busy for
a coupla days and confuse you for a month
