Montana Fly Co.'s Tungsten Thin Mint is a variation of the Woolly Bugger, weighted with a tungsten bead that gets the fly down fast in deeper runs and faster water. The signature stacked marabou tail gives it the movement trout can't resist, and the profile fishes well anywhere trout eat subsurface. Available in #6, #8, #10, and #12, it covers everything from bigger water down to smaller streams — strip it through runs, swing it through tailouts, and let it sink into the slots where fish hold. A go-to bugger when the water calls for weight and a pattern with a record of fooled trout.
