Decent line

  • Familiarity:I've put it through the wringer

If you're new to fishing, it will be fine. However, I found that after trying to cast anything more than about 20-25 feet of line, it wasn't very smooth. For short casting, it was great.

For the price, you can't beat it. But I invested in the Rio Gold and was much happier. But also paid twice as much :-O


Great line, great value!

  • Familiarity:I've used it several times

The RIO Mainstream line is a great value and a great line. Easy to cast, stays clean and is a solid line for the money!


Great Line for the Price

    RIO makes great products and this fly line is no exception. Casts well, and stays clean even in dirty water. Worth the investment.
