RIO Mainstream Sink Tip Fly Line
RIO’s Mainstream series of fly lines are designed for average and novice fly fishers. These lines feature slightly heavier and shorter head lengths to optimize rod performance. Each line undergoes the same rigorous production processes and quality control standards as all RIO fly lines and is manufactured in RIO’s Idaho facility.
Constructed with a slick coating on a supple, memory-free core, the Mainstream line delivers consistent performance and smooth handling.
NOTE: This line does not have welded loops, which are the most expensive component in a fly line. The absence of welded loops contributes to the lower price.

I bought this line for my beginner fishing trips. The cast is smooth and the line holds up well in light to medium wind. No welded loops, so it’s a good value for new anglers.

Works well for small streams and still water. The color matches the environment, making it easier to spot fish. A bit heavier than I expected, but that’s fine for my rod setup.

Great for someone just starting out. The memory-free core feels responsive and doesn’t tangle. I appreciate the no-welded-loop design—it’s cheaper and still performs well.
