FAQ
What is the difference between the level and double taper versions?
The level version is optimized for tightline nymphing with minimal sag and is FIPS compliant. The double taper version has a slightly larger belly to allow overhead casting when needed, while maintaining a .022″ tip.
Does the line have any memory issues?
The braided core design minimizes memory and line sag, providing a more consistent and sensitive connection to the flies.
Is the line suitable for dry fly casting?
The double taper version is designed to allow dry fly casting when needed due to its slightly larger belly, while the level version is optimized for nymphing only.


Caroline Short –
The line feels very smooth and responsive. I’ve been using the level version for tightline nymphing and it performs well in windy conditions. No sag, and the sensitivity is excellent for detecting subtle bites.
Joe Skinner –
Switched from a standard nymph line to the double taper version and found it much easier to cast overhead. The .022″ tip maintains good performance while the belly helps with dry fly transitions.
Donna Greene –
Good sensitivity and consistent casting. The line holds up well in cold water. A bit more expensive, but worth it for serious anglers who need precision.
Jason Newman –
Used it in a variety of conditions and noticed less line memory than previous lines. The braided core makes a noticeable difference in feel and responsiveness during long casts.
