Bianchi Volpe is a very nice ride as well. All Steel. Lightish for touring steel and not expensive compared to a Trek 520. Has double braze-ons on the chain-stay and braze-ons on the cro-mo fork. Tiagra brifters and Deore 9-speed rear. Only problem with Tiagra Shifters, IME, is the gear cables interfere with larger bar bags.

If you plan to ride mostly road, you could switch the tires for a 28 rear and 25 front. 32 on the front will not go 35mph well in a turn (downhill)!

If I were going to do tours again, I'd buy one tomorrow and swap a number of things off (Brooks saddle, tires, etc.), and of course, add fenders. It also has the fuel bottle braze-ons for white gas.

If you have no desire to tour, the sport bike option, including the Felt you mention might be the better way to go. However, on long rides like brevets, a rack may prove very useful. I'm not a fan of seatpost racks, personally.
