The Prince Nymph is a firm favourite with all Argentinean Sea Trout guides.   One of the most widely used Sea Trout flies during the day light fishing hours.  Very effective across all the sizes and with the edition of a double bead head to give it added weight this is an essential fly to have for getting down quickly to where the Sea Trout love to lie under the innumerable cut backs of the Rio Grande and Rio Gallegos.
