Our verdict

A full sinking fly line with a straightforward weight forward taper, worth considering if you need a dedicated sink line and don't already have data on how it casts or holds up over a season.

Overview

This SF fly line is a full sinking, weight forward taper line for freshwater fly fishing, sold in WF4 through WF9 weights at 90 feet, with a choice of IPS3 or IPS5 sink rate.

As a full sink line rather than floating or intermediate, it's built to get flies down to depth for freshwater species, with the weight forward taper concentrating mass near the front of the line to aid casting. Available data is limited to line weight, length and sink rate options.

  • Full sinking line construction
  • Weight forward taper design
  • Available in WF4 to WF9 line weights
  • IPS3 or IPS5 sink rate options at 90 feet

Who it's for

Aimed at freshwater fly anglers who need a line to fish subsurface rather than dry flies on top, and who want a choice between two sink speeds for different depths or conditions.

Pros and cons

Pros
  • Available across WF4 through WF9 weights to match different rod setups
  • Two sink rate options, IPS3 or IPS5, for different depths
  • 90 foot length suited to freshwater fly fishing
Cons
  • No available buyer feedback yet to confirm real-world castability or durability

Performance notes

The weight forward taper puts more mass toward the front of the line, which is standard for helping turn over larger flies and cast into wind. The IPS3 and IPS5 options refer to different sink rates, letting you pick a faster or slower descent depending on target depth.
