For years, the GPX taper was the benchmark in the Scientific Anglers collection, capable of everything from casting small dries to launching large streamers. However, every great product eventually evolves. Enter the MPX taper, built a half-size heavy and designed to pick up where the GPX ended. With more mass concentrated at the front of the head, the MPX maintains the GPX’s strengths while enhancing presentation. It retains its power, but with a touch more finesse.
