Ok, I'm on a bit of a budget and am trying to make my Tom Bihn purchases carefully. I'm looking at travel bags (a struggle between the Tri-star and the Aeronaut) a day to day bag (I love the synapse, but not sure it's professional enough) and a laptop bag that I can use daily, would be formal enough for interview situations, and could be my secondary travel bag / personal item for when I just can't make it with one bag. So... the Western Flier? Will it fit under airline seats? Is it just too big for a laptop bag (I'm 5'10" 190)... Thoughts?
