I'll throw my lot in and say: Renee. All the way.
I've seen TP's stuff going all the way back to when they began, even have a few of their first efforts on VHS still, and even though Lily is off-the-charts ticklish, as in "I don't know how she can stand it anymore" ticklish, it's just Renee has that sexy mature laugh and holy cow, THE BEGGING!
In any other contest, it would be Lily, but in this particular one, I'm going with Renee! She's the top!
