I've been trying to figure out ideal storage and carry since I started.
Used a foam box, but the bottom hackle gets crushed, and they'd fall out. I hated the foam.
Used a Flambleu slotted box without the middle leaf, lots of wasted space and kinda heavy.
Used a fake Wheatley, very annoying.
Used a couple of six box generics pressed together, better but bigger and inefficent.
Bought a generic little plastic thing with (mostly) individual flip lids. This might be perfect if you don't carry alot. Its small, compact, and light. The compartments are big enough I've got 4 or 5 of every generic pattern I'd imagine I want in a day, plus spaces for the wet stuff too.
Compartment boxes are nicer, if you don't mind the lack of anal retentivity when it comes time to categorize. I figure I'm going to try and use my little box for now, and I'll work on filling out the bigger ones to keep aournd should I go somewhere I might need to break out of the usual flies.
