Animation is about all I use Poser for.  My approach: create the animated scene in P6, sliding rows of keyframes around in the animation graph if I need to alter relative timing of one or more body parts or figures or props.  Use P7 only for rendering the animation.  P7 renders animation frames in firefly about twice as fast on my rig as P6.  But by building the scene and running dynamics in P6 before importing to P7, I can avoid P7 problems like the "point at" bug and issues around multiple cloth sims.  Someday if some of these P7 bugs get fixed I'll re-try building animations in P7 and give animation layers a try.  However, my sense from P7 SR1 is that problems faced by animators are given lower priority.
