SA tricolor sighter
20-30 hours of use later, using 2X as a 25' long leader, the colors that were usually off the reel were dramatically faded. This is considerably faster fading than I experienced with Umpqua bi-color sighter, and I haven't used Cortland's sighter enough yet to compare it. I don't know if Devin agrees.

Used 2X with a 2' piece of 2x Cortland gold added today for comparison. For my rivers' backgrounds and thru my eyes and yellow lens polaroids this material is as visible as the Cortland gold, which itself is as visible as 2x Umpqua pink and green. It's gold and green that are most visible to me, with no advantage obvious to me for red or pink or white. I'm trying these 2X materials as my whole long leader line. Very nice for that for nymphing (not casting unweighted flies).
