How do I choose between these girls?

Okay - last night I was playing keyboards at a gig. After the gig I got caught up with a group of people and there were these two girls who both seemed quite keen. They were both spending time hanging around, asking me lots of questions about myself and chatting a lot. They are both single and gorgeous. They seemed very nice girls.

AW spent a lot of time holding my hand, wanting me to teach her how to play stuff on the piano. Beautiful strawberry blonde. Slim and tall (as tall as me!). As we walked out she was holding my hand and being generally very friendly.

SL was also hanging around while I was playing piano, asking me to play stuff and singing while I played, coming up and cuddling up behind me. She made some comment about me possibly being her "future husband" to another girl in the group. She has light brown hair and is a bit more curvy than AW. She's a smoker (on my list of no-no's) but I've been having a bit of a mental wrestle about whether I could make an exception!
