When the first sighting occurs, I yell, "Tuber, 10 o'clock, 40 yards!" Eric brings us within range, cautious of his strokes, which can easily spook the wary fish. The rise is now almost at 12 o'clock near the cliff, and I cast. Eric ties on a big, visible hopper with heavy leader and tippet. Hoppers and unique attractors-like an oversized parachute fly that looks like a cottonwood seed-are by consensus the best flies for rising carp.
