I never met any girl while they were at EF but met three after they left. The only girl I thought was worth it of the three was Lilianna/sillygirl (Sarah while at EF). I met Lori when she popped up and was pretty disappointed in her service. I am also one of the few that was disappointed with Ari. I suspect she just had an off night which is going to happen every now and then.
Lilianna is still my ATF even though she was a giant pain in the ass on this board.
