PC World contributing editor James A. Martin experimented with one-bag travel and his
findings were mixed. It seems to me he made a couple of mistakes. First, his load was over 25 pounds. Depending on your frame, anything above 15 to 20 pounds is going to be chore before long. Second, he made matters worse by using a wheeled cart with a shoulder bag. And what he got was a tottery load that proved to be a checkpoint hassle. I’ll say it again: Don’t try to go without wheels unless you can get the weight way down. 25 pounds + is tough sledding.
