Next week I'll be staying on a Maine lake with a good smallmouth fishery. To supplement decent largemouth bass fishing I think I'm going to try for smallies on a fly rod. I've had luck spin fishing for them in 20+ ft of water but do folks think you can effectively fly fish in water this deep? I realize I could use a 20 ft leader with weight and a full sinking line but that doesn't sound like much fun. Cast, let it sink for a few minutes, twitch it a bit, repeat.
