If you could only carry one fly box....

I like to bring a wide variety of flies because at times I like to go a completely different route than the traditionalists. Matching the hatch can be fun and is obviously productive at times, but sometimes tying a #28 on 8x tippet gets old. That is when I switch to something outrageous. Last year I was catching large numbers of trout on California's Hot Creek (a heavily fished C&R spring creek) and they were taking bass poppers!!!

Cheers,
Greg

Of course this applies mainly to the West and is a generalist assortment...
Copper Johns
Bead Head Prince Nymph
Pheasant tail
Rubberleg Hare's Ear
Adams
Elk Hair Caddis
Small Stimulators, big ones at Salmonfly time, and big stone nymphs too.
In the summer add Hoppers, beetles, and ants.
Good enough for me, and I never come home empty (well actually I almost always leave empty because I catch and release 99% of the time!)
But I also carry a dozen boxes when fishing, not hiking is the goal.

My tailwater box. Scud's Midges and oddball creations. I have 12 fly boxes but this one get's used the most.

Clousers. It works in the salt, rivers, and lakes for warm and cold water species.....virtually everywhere you can fish for carnivorous fish.
