Riverboxes has just added a highly effective nymph to most Western US Riverboxes. Kevin Hurley, one of Colorado’s premier river guides, says that for many US Western rivers, the Fly Formally Known As Prince is a “must” pattern. Use a size 16 as your bottom nymph in a double dropper set up, or in a size 12 or 14 under a stimulator. Get a Riverbox for your favorite river and you will catch fish!
