I recently returned from a few days fishing on the River Tay in Scotland. I fished the Taymount beat where my good friend  and fellow Guideline Power Team member Cornelius O Dea is head gillie. Conditions were not easy but we plugged away tirelessly with the Guideline 3D  line  3/5/8 and it paid off. Great call from Con to use this line which has served him well on thar beat on numerous occasions. Check the lines out www.guidelineflyfish.com
