If you place your attractor fly first, then your small fly next, with the split shot on the bottom, do you find that gives you two water column heights to fish at. So two opportunities for the fish to see your tasty morsels. Also, does the split shot on the bottom prevent loosing fewer flies because if the shot hangs up, you only loose a split shot and not 1/2 your rig?

I am just looking at what set-ups give you the best results.

On an airplane, check a rollar duffle with clothes, waders n boots. Backpack with essential reels, small kit of flies n tools, and shave kit. Rods are in a travel tube. This way, I have the critical fishing gear with me and over night supplies just in case.
Car travel, just a duffle that carries waders, boots, dry clothes.
