Lucy/Lilly Used to be almost interchangeable. First time I saw one of them, I booked Lilly and after the deed she told me she was Lucy. Then I saw Lilly and She seemed identical in performance to Lucy except for one detail. I alternated Lucy, then Lilly for a long time, it almost made no difference, performance was so close. But now, they have drifted apart, and even though you can see either in the same location, they don't work at the same time, and for what it's worth, like with any couple break up you have to pick who you stay with, and I'm with Lucy now.
