Actually, I'm a sucker for vintage or "vintage looking" steel bikes. I'd probably go with a custom built steel bike with purdy lugs on it.
Actually, of the 4 listed, I suppose I'd go with the Madone... partly b/c it's supposed to be a good bike, but also b/c I've never own a Trek, and would get a kick out of annoying the elites by putting a "STAR" sticker on the frame.
Live long & prosper, y'all.
Felt Z5 is another good bike.
