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.
What buyers say
From Amazon customer reviews.
Experienced fly anglers, including some fishing dozens of weeks a year, say the coating resists holding memory better than lines they've paid more for, and that it casts smoothly while sinking flies into the strike zone quickly. A couple of longtime users describe the feel as plasticy and stiffer than a floating line, and one found the sink rate runs slightly slower than advertised, close enough to still be usable.
