Spring, summer, and fall usually finds us pestering in ponds, streams, or lakes and we most generally use, have faith, and search any of our targets, warmwater or troutoids, with a two fly rig. One bug is always a small dark wooly bugger (black #10-#14) very similar to Rick's Boa Leech, and a small surf candie type bug ( 1"-1 1/2" #10 white and pearl krystal flash). This seems to cover bugs and bait successfully, wherever and whenever, spring to fall, for us. Cannot answer winter.....we are ususally trying to pester coastal steelhead and either NOTHING works consistently or EVERYTHING works inconsistently....for us.
