It's hard to say who I think the finalists would be, because I'm well aware that my own tastes are not universal.
My ideal final 4 though?
Aya, easily.
Leanne, most likely.
...prolly Lucia, though she's got some stiff competition there.
Kika.
And I'd have prolly voted Aya over any of the other 3 when it came down to it.
