I have, for many. many years, used a Filson back pack. It sits nicely at the small of my back, holds flies for an entire trip, weighs virtually nothing, and looks good! For the forceps and clippers, and tippet, I'm trying to use a lanyard. Jury's still out on that. Haven't used it over a spring/summer/fall yet, so we'll see how it does in combination with my chest port! The cord will run right over the top of it, and I can't imagine it to be too comfortable! We'll see! I like the idea of the shoulder bag, but it, too, would be heavier and ride right over the port.
