Thank you for your feedback.
I have received similar feedback from other sources as well, so I'm definitely looking at the Aeronaut. As far as Red Oxx offerings, I'm looking at the Sky Train, which is tremendously expensive but also well-regarded.
Now, the only question left for now is whether the Eagle Creek PackIt! Folders will work in either of these bags. I may try starting another thread for that one.
Thanks again.
