Which type line would cast best?
I'm an average caster and I do better with lighter weights. On higher weights I sort of cant my wrist to lock it from bending and cast Lefty Kreigh style. I want to go to a 10wt fly rod for Salmon next fall and strip streamers and leech patterns with maybe an egg dropper. I would be sight fishing from a boat casting 60'-70' or so to Salmon holding in 3'-6' of rather swift currents.
I need to get the pattern down fairly quick but I'm confused which fly line to use - sink tip type III, sinking line, shooting head/taper. Whatever line is best I would rather it be one piece at least 90' or so - I don't want 30' of something that has to be attached to a running line. Any help would be appreciated, thanks.
