20% thinner than a comparable line. Extreme distance into winds yet lands like a delicate silk line. A triangle taper line that is extremely stable even with lots of overhang. Popular in Scandinavia for coastal sea trout and fisheries that feature strong winds. Essential when distance and presentation are required for small to medium sized flies / multiple trout size rigs. The goto line for UK stillwaters from bank or boat. The original International line that Sunray made for Arctic Silver Innovations.
