I want something triangular-shaped like these bags, and I know I'm not a brief person (since I've tried it IRL -- too flat for me). The step looks so great, but I like slightly bigger bags and in photos it reads medium/smallish. And the RTT looks absolutely huge, as well as heavy. My favorite style is the giant day, if that helps. The city feels smallish - the work is okay but I want something less rectangular. What do you recommend?
