A lot of folks claim to have mastered it and brought it under control. Of course, a lot of folks in 12 Step groups also make the same claim for their specific problem habits.
All should be taken with a grain of salt..:)
I love Lee's replies. Always worth reading and sometimes very funny. The one above qualifies as both.
Here's what I do. Years ago I made three fly boxes from the pill boxes as described in the book
Midge Magic. Each box has 7 replaceable rows of 4 small compartments with individual lids, each marked with the fly and size. I made covers for the tops of the boxes out of the plastic packaging, creating a hinge, and painting everything brown on the outside. The covers keep me from accidentally popping one of the compartments open and dumping flies accidentally. I then cut one box in half creating two small boxes, one with 4 rows the other with 3. In any one of these boxes I can pop out any one row of four compartments and replace it with another, depending on what I think I'll need. Walt's worms and green weenies rarely, if ever, leave their box though. I have about six extra pill boxes that hold flies not in use, all stored in the original clear plastic packaging to keep them easy to view and safe from dumping. Flies that can be stacked in without damage, such as nymphs, caddis, most terrestrials, and small dries such as olives go in these boxes and each box is tuned for the stream and time of year so I have what I may need in them by replacing individual rows from the storage boxes. Then I have larger hatch boxes, either commercial C&F waterproof boxes, or medium boxes with bristle tack. I have one large C&F box with early flies, mostly hendricksons, but also blue quills, olives, apple caddis, tan caddis, and one or two craneflies. Another C&F box contains sulphurs and cornutas mostly, with a few caddis, crane flies, etc just in case; another with slate drakes and cornutas and a few assorted just in case flies, such as October caddis for autumn. I have a large bristle tack box with green drakes and coffin flies; a smaller bristle tack box with March browns, etc. etc. The hatch boxes typically have all forms for mayflies, nymphs, wet flies, duns, and spinners, as needed, and adults and iris caddis emergers for caddisflies. I also almost always carry some caddis in the convertible boxes in mixed colors and sizes, both adults (mostly cdc) and iris caddis.
I like Lee's system, but am possibly too lazy to keep it all straight. I do switch out the rows in my convertible boxes, but I'm afraid with Lee's system I'd fail to replace the flies from the smaller boxes into the larger ones, and, as he says, promptly have a mess on my hands. But, as with vests, packs, etc. we all tend to find what will work in our own way. So far so good for me with this . . . but I'm always thinking there has to be a more efficient, easier way. Maybe . . . maybe not--for me.
