Thanks, everybody, for your sage advice.

Due partly to your comments, I've corroborated my opinion that the Fulcrum S5s are not the upgrade I'm looking for. It's really tough to get good info on the S5s, so knowing that they are roughly equivalent to Racing 7s is very helpful.

I've decided to give the RS80s a try, as I do have the luxury of giving them a road test. If they're too flexy I'll keep looking but my reliable mechanic at the LBS thinks they are going to do me just fine.

Thanks again, all.

And happy riding!
