The Henryville Special is an older fly pattern, but one that comes in handy for a caddis or blue winged olive hatch. It can be a bit tricky to get the wing slips to sit nicely, but a bit of practice will help you get the hang of it. I’ve been putting together a new box of flies for the spring opening and hope to include a few HvS’s in the mix. If you want a little more durability in the fly, I would suggest adding a reverse rib of fine wire over the grizzly hackle.
