Double Thin Mint Olive - Tungsten Bead - A great fly by itself, consider this doubly effective! Gets down to where the fish live, and has a great movement in the water. Proven. Effective. Get some!
I've had lots of success with the Double Mint. Tailwater, small streams, lakes - I've caught trout in all of them with this fly. I've even had a Walleye take it!
