These tips are 10ft long, and have a steady front taper of about 3ft, which allows for good presentation of a fly. Each tip has a color coded loop at the rear, and is printed with the tip size - attach the printed end to the fly line. The tips are built on RIO's ultra-low stretch ConnectCore for the maximum in sensitivity and performance, and are density compensated at the front end (not the intermediate) for the best fishing performance.
