Works as advertised. As supple and turns over as well as standard Powerflex, but greater tensile strength permits you to use at least one size smaller allowing for more delicate, stealthy presentations. I purchased a 6x to try it out with small (18-20) BWO dries. Presented like a 6x but performed like a 5x horsing a 19" Brown from under a submerged log without breaking him off. I will order more.
