RIO MainStream Floating Fly Line



When it comes to an inexpensive floating line, RIO's MainStream lines are the best we have seen. At Pacific Fly Fishers, we consistently try to bring you the best products at each price point.

The tapers and line weights RIO MainStream are designed with the novice in mind and result in a line that optimizes rod performance at short to medium distances. However, just because this line is designed for newer anglers, it still incorporates the qualities that have made RIO lines so popular, like minimal memory, slickness, durability, and floatation. In addition, MainStream lines undergo the same rigorous production processes and quality control standards as all RIO products. If you're looking for a quality floating line without the $70+ price tag, choose the RIO MainStream and you won't be disappointed. Length is 82-feet. Color is Lemon Green.

  • Slightly heavier, easy casting lines for a multitude of situations
  • Short, powerful front taper for good presentation and turnover
