This dainty little fly has been a standard in my box since I created it. I landed my first true 20 inch rainbow trout with this size 18 beauty. The tail is an antron yarn shuck, with a olive goose biot body, the post is a folded over CDC tuft feather, with a para style hackle, with sparkly olive dubbing. Size 18 Klinkhammer style hook. Best fished with 5X tippet and used for those sneaky sippers in the back eddies, seams, and riffle tailouts in the early and late season. MMmmmm…little mayfly fishing.
