(en)From small streams and spring creeks to tail waters and Western rivers, the Precision Platinum was designed from tip to taper to cover the full range of trout fishing conditions and challenges. A longer head, extended rear taper, and larger diameter running line give you the maximum line control, both in the air and on the water. Built with a low memory jacket that stays supple in cold water but doesnt wilt in summer heat. Plus, the 3-foot, high floating Dyna-Tip (with a welded loop) floats higher and lands more softly for the ultimate in drag free drifts. Cortland -Precision Platinum-. The best casting, the best floating, best fishing, all-round trout line ever!
