Overview
A floating trout fly line from RIO's Mainstream series, built with a slightly heavier, shorter head so casting comes easier for novice and average fly fishers. A welded loop at the front speeds up rigging to your leader.
The short, powerful front taper is built for turnover and presentation rather than distance casting.
- Welded loop at the front for fast rigging
- Short, powerful front taper
- Built specifically for freshwater trout fishing
- Priced below flagship fly lines
Who it's for
Novice to average fly fishers who want a smooth-casting trout line without paying flagship prices. Not ideal for anyone who wants welded loops on both ends straight out of the package.
Pros and cons
- No welded loop on the backing end, so you'll need a knot or add-on loop
- Some coil memory noted fresh out of the package
Performance notes
The short, powerful front taper is built for good turnover and presentation, and the front welded loop lets you attach a leader without tying a nail knot. The heavier, shorter head design is meant to make casting more forgiving for anglers who aren't chasing distance.
