Murray's Heavy Hellgrammite Bass Fly Assortment When big smallmouth bass go deep, so should your fly. Murray's Heavy Hellgrammite (designed by Harry Murray) is tied with ostrich herl — a material that pulses and mimics the naturals in the current far better than marabou — and weighted with a heavy lead eye to cut through the water column and get down where the fish are holding. Designed to match the dobsonfly found on classic Appalachian smallmouth rivers, this assortment gives you the full color and size range to match the hatch all season long. Often by mid-July you can expect to see the adult dobsonfly and their eggs in the trees along the stream banks on the Shenandoah River. This fly has been a true staple in our fly boxes from Spring to October in Virginia. This fly assortment ships in a labeled 6-compartment fly box so you can easily reorder individual patterns when needed.
