I almost always tie a dropper when fishing a popper or large foam fly. I usually go with a much smaller fly about 18" to 24" below the surface fly. I like midges and small nymphs that represent another normal food that is present in the water. Scuds, Hares Ear, Pheasant Tail, etc. Even very small jigs in the 100th to 180th ounce sizes work great.
