Bumping to see if anyone has any comments...

I actually bought this bag over the weekend but it'll have to remain in the box for the next couple months until I can use it.

The demo looked good in the store. Seemed a little hard to zip the backpack to the roller when both were empty and I figure it would be a little more difficult when both bags have things in them. This was confirmed by a couple folks in the Costco.com reviews. It nonetheless still got 3 5-stars and 2 4-stars.

Also, the price is really good at Costco ($50) so worth trying. It's $120 at the official ful web site and $96 (until 08/25, then $120) at eBags.com.
