What, no Ashley Robbins? BLASPHEMY!! :) Good size and proportions, and a nice tan-red hair color scheme to boot.
Out of that list, I'd say Jenny McClain. Chikita's look really nice, but I don't have any of her cards yet so I cannot give it a fair vote. Marta's are also very nice too. I would say Zuzana, but her nipples are too small to me.
And honestly, I think Laetitia is really overrated. I have one of her cards, and she is pretty good, but she definitely does not have THE best set on VG.
