Hmm. In the last three weeks I have taken two trips with the same bag set up: an LL Bean Turbo transit backpack and a B&R satchel. In both trips each bag weighed 14 pounds and I thought it went fine. I didn't take a roller since both trips were on the Acela and rollers aren't as convenient there in my opinion. I even walked from the station to my hotel this past Monday with that carry. Not a long walk, but didn't think twice about it. I do think two 14 pound bags are a lot easier than one 28 pound bag.
