Madone of course! The geometry differs from LeMond, but I'm guess your LBS could set one but nearly identical to your LeMond. From my limited rides on Kim's 5.1, the frame is AWESOME! Keep your Reno for a rain bike, I'm guessing you'll love carbon.

That said, there are tons of great bikes out there. Even though I've never ridden one, I would have a Cervelo R3 near the top of my list. The new Specialized Roubaix is suppose to be killer - see lastest Bicycling Mag. I also like the idea of custom and TI. We have Roark near Indy, building some beautiful TI bikes, also LiteSpeed has a custom group now (I forget the name).

Your RAIN performance was EPIC, and it's not about the bike, but it's what you do and enjoy, if you have the means why not ride a great bike. I still enjoy my Madone, I like to clean it and very much enjoy riding it. Yes it cost 3 times the Cannondale it replaced, but why not. I loved the Cannondale as well, but almost always grabbed the Madone when going for a ride.

Bike Shopping = BIG FUN! Take your time and have a blast.
