done all my ST fishing there with my 5wt, but in the lochs Kirbister and Stenness,my pal fishes with a 6wt, they were on Hoy this year with some decent fishing in the sea, He said it was like fishing the Florida Flats watching the trout moving across the sands, but this was in May, which he considers to be the best time, but tight lines, I hope you get the weather , Derek Roxborough
