RIO® Mainstream Trout fly lines are targeted to the overall needs of the fly angler - an excellent choice for day-in, day-out angling. MainStream fly lines are designed to optimize rod performance, with shorter heads, tapers and running lines that empower the novice to make the cast.
The MainStream floating lines have a supple self-lubricating coating that remains memory-free in cold water. MainStream lines undergo the same rigorous production processes and quality control standards as all RIO products (made in USA).
If you need a low budget fly line, this is way to go!
