No wheels? That's nuts. I would NEVER get a bag without wheels. I couldn't find where he said that, so I don't know why.
The other best thing about this bag is that they have a 100% unconditional warranty. So if you break the wheels or accidentally chainsaw the bag in half, they will give you a new one for free.
I would definitely go with the Switchback 22 over the Voyageur - it's the same size + the additional backpack if you need more space / versatility. The support harness on the switchback is at least as comfortable as the Voyageur I'm sure.
