This line performs beautifully on both dry flies and nymphs. I’ve used it for trout in clear streams and it casts smoothly without tangles. The mending is excellent, and it handles long casts with ease. A reliable choice for my daily fishing.
Dan Kerr –
Great for small dry flies on picky risers. The smoothness and true-to-grain-weight feel make a big difference. I’ve been using it for several weeks and it still holds up well after repeated use.
Adam Baker –
Solid performance in both distance and accuracy. Works well on bamboo rods. A bit heavier than expected, but that’s fine for my fishing style. Would recommend for trout and panfish.

The Infinity taper allows me to cast far without losing control. It’s especially good for glass rods and delivers flies with precision. No issues with tangles or breakage so far.
