Winston's salt and freshwater Boron II-MX series. The MX stands for "MaXimum", as in maximum power, distance and fish-fishting capabilities. The 4, 5 and 6-weights are slightly stiffer and faster for more aggressive fishing. The 7 through 12-weights are true "cannons" that can handle sinking lines, big flies and adverse wind conditions.  While all models feature faster actions and are capable of long distance, 100+ foot casts, they will amaze you with their responsiveness and light weight.  The rods come with a cork fighting butt and Winston's new double-locking reel seat.
