Tungsten San Juan Worms are one of our favorite patterns, especially during higher water conditions. The weight of the tungsten bead helps get you down, and the two-toned body gets noticed by the fish. You can tie this fly in a number of color combos, but brown/pink, red/pink, and brown/orange are some of our favorites. I have yet to find anywhere that this fly doesn't work - tie up a few and give them a try!
