Leaders: These monofilament leaders are well tapered and turn over clean. Not to soft and not to stiff. A very good leader for fishing large to small dries. Not much of a problem with twist (matching fly size and design to your tippet size is critical with all leaders). The Precision 2 leaders are a very good choice for dry fly fishing at almost any range.
Tippets: We found very good knot and over all strength with the Cortland Precision 2 tippet material. Turned over nice and had little to no problem with twist (matching fly size and design to your tippet size is critical with any tippet material).
