I had loaded on a 9 wt. Cortland Clear Rocket Taper Intermediate Line and tried it out in the cool water that we have. It casts real nice. A little bit stiff because of the cold but tangling was not a problem. Slicker finish then the Airflo, tangles less then the Airflo, and feels better in the air to me then the Airflo line. Just my opinion. I had used the Airflo for the past 3 years.
