just a mention- personally, i use the free easypose tube 2.0 by ajax for all my tubular needs.  i find it very easy to use.  if you just make an add-on freebie texture or maybe full pose if not character (ask ajax) to group multiple ones how you'd like, you'll get the tube functionality and an opportunity to advertise through freestuff (as i notice many do).  right now ajax's stuff is down (rendo is saying his bandwidth is done  for the month), but i'm sure that will change.  actually, i wonder why there's a run on his stuff now as his latest freebie in freestuff is more than a year old.  could be anything, i guess.
