Photo comparison sought: WF-Aeronaut-Tristar
The graph of interest in these bags I think would justify some all-angles comparison shots of these bags next to each other :) (top / back / sides / on a few people of varying stature)
Maybe also a sample load-out shot, showing the bags fronted by a stack (contents arrayed so as to be easily discerned) of what they can hold with a full but reasonable packing job.
Probably best in a color that they all come in, so as to remove that sometimes emotional distractor ;)
