Here is the most recent version of how I prefer to carry my flies....mind you I carry way to many, but they are all in a Simms Headwaters Guide hip pack so I have plenty of room
I use the small windowed ones for midges.
Small box #1 = non beaded midges, such as rs2,jujubee,blood midge, disco midge (all tied by me)
Small box #2 = small bead head midges and emerger such as Barr Emerger,rainbow warrior, purple poison tung, two-bits etc etc (all tied by me)
Big Simms Box #1 = Big nymphs such a Pheasant Tails, Hot Wire prince etc etc and some dries (PS it is full now) All store bought flies for now
Small Simms Box #2 has about 80 parachute adams and big PMX, Golden Stone, EHC , Worms etc etc (all tied by me)
And yes I get it, I carry way to many and I do separate by store bought or home made (it is nice to know).
