I was upset about the eyebrow thing, but as suggested, having textures where the brows are on a separate layer would work.

I did a side by side comparison of V3 and V4, actually used a V3 pose on V4 so as not to show biased...yeah, right. Anyway, I found tweaking the pose for V4 didn't leave me pulling my hair out.
I also discovered that V3 isn't quite the queen of heap. V4 clearly is superior in form.

V3 has been around for what...4 years now. V4 was released a little over 24 hrs ago. Four years down the road, V5 is going to have a tough act to follow. 

I'm coming around.:)
