Quote - I don't find it any less time consuming to rig prop shoes over conforming.  And, the time savings for the end user is worth every second.  To me, anyway.

As for the one shoe on, the reply above covers it.

Just thinking of the times I had to turn conforming shoes into prop shoes because they were designed to conform to a different figure than the one I was trying to use them with...

As far as one shoe goes, aside from being in jest, it really isn't much harder to copy/paste materials from one to another than to hide one shoe in the heirarchy, but then I have to remember that we might not all use the same approach or know every feature to the same degree.  I am always forgetting the whole vendor/user aspect of things...  If I were selling content I would always try to consider what the majority of my market preferred using.  Just didn't see the time lost in using one method over the other because I was thinking of my own usage and not that of customers. 

I would more likely buy an item that worked with all of my figures than one that only worked with V4 (or whoever is popular this week) just to save a step or two when using.  But I don't buy much anyway, so of course I prefer things that are versatile enough to work however after some tweaking.  I suppose if I were buying an item I would just want it to work immediately.
