This is going to be our new favorite for fishing streamers and big nymphs rigs on big rivers! The Big Nasty replaced the old PowerFly, which was one of our favorite lines as well. The InTouch core on the Big Nasty is a big improvement, and allows you to feel softer takes and have a more positive hookset. Here's what RIO has to say about the Big Nasty line:
The InTouch Big Nasty is designed specifically to cast large and heavy flies with exceptional ease. The line features a short, powerful front taper that has no problem casting weighted streamer and large terrestrial patterns, and is heavier than the industry standard to load modern rods quickly. The line is built on RIO's ultra-low stretch ConnectCore for the minimum of stretch and the maximum in performance, and features RIO's XS and AgentX technologies, as well as welded loops on both ends.
