Judy never seems to get any love- but with a few easy morphs, it's quite possible to get amazing results with her. When I was using P5, a modified Judy was my character of choice. The nice thing is that she comes complete with a lot of morphs (no need to buy add-ons like with V3/V4) and works well with Poser's face room, etc.

I just upgraded to Poser 8, and while I haven't loaded up any of my P5 characters, I have been working with getting a good "go-to" Alyson character. (My wife saw my first few P8 test renders with Alyson's default face- her comment was,  "Scary," and I tend to agree...) There's some good morphs, but I always like to tweak things a bit more myself.

If there's one complaint I've got, it's the lack of decent additional skin textures for the Poser characters. I know there's an Alyson skin with makeup on out there somewhere...
