I've used Scientific Angler fly lines almost my entire fly fishing life, of now over 40 years.

This past year I bought an 8 wt Rio Outbound for use on my 9 1/2' 7 wt Sage XP, to use here in Montana, primarily for the large streamers that we are beginning to fish more and more as Fall progresses.

For big fish on big streamers in big rivers, I give this line a BIG thumbs up!
