My exact thoughts. I’m on flight bag iteration number 5 and nothing is quite right. Basic non aviation Samsonite laptop bag worked at the regionals till I figured out what I needed, then an e-bags that was useless. I moved to the big aerocoast ii on the CRJ and it was overkill, plenty of food storage but not the right mix of flight bag storage. Got a LW cube that was almost right, but went to the guppy and it’s just too wide and my seat can’t slide all the way out to gain easy access. Currently running a contrail 410 and it’s good, but the lack of organization in the main compartment is its huge drawback.
I’m also weighing what to replace my LW stealth brick

-house with. It’s just too heavy, and I don’t even pack that much crap. Paradox was a contender but the lack of J hook sealed that. Just had an FO who had a B&R spinner that annoyed the crap out of me trying to stack my bag around it, it was massive. Looked at strong bags but it doesn’t appear to give me much in weight savings. In my 3 little bears story, my porridge keeps being too hot or too cold.
