Thanks to both you and deepinhale for the quick replies. SSW Vanessa seems to be extremely popular, but she has kind of a "hard" look to her that's a bit of a put off for me. Maybe what I'll do is try the the clip that deepinhakle mentioned that features both Vanessa and Jessica.
As far as Random Snaps goes, I have quite a bit of Shirin footage from her days at SmokeVision. She's great and maybe eventually I'll buy some newer HD stuff from RS, but right now, I'll probably experiment with models I haven't seen.
Both you and deep inhale mentined JasmineP. I already had her in my notes as a woman who "looked" the part, so I'll have to try an episode with her in it.
