I used to try and choose who I thought I would have the most fun with and for the most part I wasn't disappointed. But a while back I had a very unplanned double that was a) with a provider I probably wouldn't have seen for quite a while and b) totally amazing. Maybe my wish list would be "you and your choice"

I guess that works both the "you know what I like" and the surprise factor at the same time. Granted I wouldn't want to be bombarded monetarily with doubles all the time. And I do enjoy one on one more often than the double fun.... but occasionally? Oh yeah - just don't make me choose.
