I have old wool fly wallets I inherited but I find that I miss good flies in them because everything jumbles into one dense mess of feathers. The wallets also smash some flies that I wish they wouldn't and I lose flies from them every once in a while. I am interested in what is the best box going as of now for big salmon/steelhead flies. There are so many new designs when I look through the options. The one that has really caught my attention is the C&F Design fly boxes with the microsplit foam. This seems like a good concept but does it actually work in the field? Will all the flies just slip out the splits when I am tromping around a river? Any input is welcome! Thanks all!
