The 'Bead Head Prince Nymph', also known as the 'Brown Forked Tail' catches fish all the year round. It was developed by Doug Prince in CA in the 1930s for fishing his favorite stream the King's River although today the design has moved on a bit from his original. It's something of a classic and a must have in your fly selection.
