The most popular egg fly. I use the KoreaSun 7057 hook in size #6, 8, 10. Most colors have a contrasting spot color. Clown patterns have 4 colors. Flame works best by itself.
Egg patterns are best fished dead drift, suspended near the bottom, under a strike indicator or bobber, with split shot 30 inches from fly. When bottom bouncing with lead, use long leaders 5 to 9 feet between lead and fly.
