Considerations & Trade-offs
- At 0.3mm, this wire is sized for heavier patterns, so it may be more than needed for very small or delicate flies.
- The March Brown color is specific to certain tying applications, which can limit its usefulness if you need a more neutral or highly contrasting body color.
- The spool contains 10m (10 yds), so frequent tiers working on larger runs of flies may go through it quickly.
- It is described as non-tarnishing copper wire, but that still leaves the final look and finish dependent on how it is used in the pattern.
