If I've restored it, and it's in good, safe condition, I ride it. Period.
Now, the conditions I ride under will often determine what bike I ride. Best instance is if I'm going to do a day's ride (50+ miles) and there's a good chance that I'll hit some rain in the process, my Rossin is definitely staying home, my Tour de France will probably stay home, while the Magneet and Trek 460 will be the rides for the day.
And if it's going to potentially be a real nasty day out, I take the Trek 2000T - it's powder coated and aluminum. I could care less what the weather is.
