Diya and Maxi might be the best choice from what I've read. I haven't seen them myself but I know someone who saw Diya and he said she has a pretty face and a nice body. She likes to give bj's for a long time though and you might need to take the lead.
With the other new girls, Maxi, Sienna and Lila, Maxi might be the best choice since the other 2 just looks older from the pics alone but personally I'm intrigued with Lila's pics as well even if shes older looking.
