Our verdict

A reasonably priced full sinking fly line that casts smoothly and resists memory, a fair pick for stillwater and streamer anglers not chasing premium-line suppleness.

Overview

A weight-forward full sinking fly line, sized WF4 through WF9S in a 90 foot taper, with a PVC-coated braided core, welded loops and an IPS3/IPS5 sink rate for streamer and stillwater fishing.

Anglers who've fished many different lines describe this one as slicker and less prone to coiling than pricier alternatives, and several say it casts smoothly straight out of the packaging without extra dressing. A couple of longtime fly fishers call the coating stiffer and less supple than a floating line, and one notes the actual sink rate runs a touch slower than advertised, though still workable.

  • PVC-coated braided core with welded loops
  • IPS3/IPS5 sinking rate, WF4-9S sizing
  • 90 foot weight-forward taper
  • Ships pre-loaded on a spool

Who it's for

Suits anglers targeting streamers or nymphs in stillwater or moderate current on a budget. Less suited to someone who wants a supple, easily-stripped presentation line or needs sink-rate precision matching premium lines.
