Maysoon for me...Rachel is fairly pleasant, think that Sarah would get on my wick after a while...and as for Lisa, if you spent a passionate evening on the rug in front of the fire with her she would probably melt!
If Sara didn't have such a ridiculous voice then I'd say her but for the purposes of this poll I have voted RACHEL who seems like she could be decent girlfriend material, if i was given a few months to corrupt her first.
