Quote - Best modelling package for Poser?

Ain't no such animal.  The best for me could be useless to you and vice versa.  I use Wings and it's absolute simplicity to learn and use.  Don't be fooled by a price tag; a modeller that is capable of making what you want with the minimum of hair tearing out is the best one for you.  

Wings is surely a contender for best program to use with Poser.  It works with .obj format so it is easy to get models back and forth without to much loss.  It is very easy to set your import/export scaling factors so that objects are a workable size.  It imports and exports without changing an object's position or vertex order, and uses the same axes convention of Poser (vs. blender).  Maybe a few things would be better if they were specifically trying to be the best modeler for Poser, but that was never the specific goal for Wings.
