+1 on the Conti GP 4000s. I first bought them after tiring of rear-wheel flats. I am on my 2nd set now - replaced because the 1st set finally wore thin, but they never had a flat. I also feel much more confident in the rain, going over gravel.... in the Conti's than I ever did with the stock Bontragers that came with the bike.

Kermit - for the trainer, I bought a cheap 2nd-hand wheel that had the same derailleur on it as my regular wheel, put one of the crappy old Bontrager slicks on, and just swap out wheels - rather than ruining my Conti's or dealing with changing tires - when I use the trainer.
