Fly line for cold saltwater fishing.
I fish in cold saltwater in Scandinavia for seatrouts. Fly size from 4-10 well dressed. Distance is somewhat important, 20 meters is enough. Has to be a floating line. What line do you think would do this well? My rods are Sage One 691-4 and TCX 790-4. I have shooting heads, but I would like a wf line suggestions.
