Don't know what to tie on? You might consider this one. It is a great nymph to use to search for fish. This fly was named after Doug Prince for fishing his favorite stream, the Kings River in California. Since then it has been successfully used all over the globe to do what it was made to do, CATCH fish! We added the Copper Bead Head for extra weight and as an attractor. I always carry a few of these in various sizes. It works great as a top nymph in a dual dropper setup. Now's your chance to fill your fly box with this staple fly.
