T-7 Premium is created from carefully selected materials to achieve the best balance among tensile strength, shock strength and abrasion strength. For bass fishing line, the key quality attributes are fatigue resistance for repetitive castings, shock strength while fighting fish and shock abrasion strength for fishing around structure. To achieve the ideal balance of these three types of strength, T-7 Premium is made from high quality and carefully selected materials and produced using the manufacturing method which maximizes the attributes of these materials. This exclusive manufacturing process gives T-7 Premium a perfect molecular balance that results in unmatched strength. In addition, T-7 is put through a heating process that gives T7 Premium natural translucency, as well as the suppleness for better casting distance and control.
