I have been using this line for almost a year now, the amount of fishing i do, throwing it into debris and whatever else is laying around it gets beatup but it is my own doing. When im open casting it lasts, very strong. I have landed many large stripers on this fly line including a 49" 35lb13oz striper. I purchase the WF10-S as well. The price is right, and for my fishing it outlasts the big name brands, you know what they are. I get an occasional tiny bubble in the line (right out of the packaging), but for the price and amount of abuse I give them, it doesnt bother me at all. Extremely smooth casting and shoots far!
