Hey Floater, The flies themselves are just a small piece of the puzzle when going after steelies with the fly rod. Spend more time working on your presentation of the fly, and no, your fly does NOT always have to dredge the bottem to get those winters fish to hit. If your fly is swinging +/- 6 inches above the rocks your close enough to the zone, no need to be bouncing off of the bottem. Some of my most aggresive hits on the fly have come from some very fresh winter fish. Spend time on the water, don't give up and good luck, cause there is nothing more rewarding then that first steelie on the flie.
