Re: surf fishing running line preferences
I'm using Zpey fusion 0.28 coated running line. It tangles a bit, but It's great for my seatrout fishing. If you want a mono line then I've heard good things about Zpey zpeed running line. Personally I don't like mono running line since it's so hard to grip and slip in my hands.
For shooting heads i can recommend Zpey Unique, I have one in an 8wt (18gram) for my Sage TCX 9' 7wt. It works flawless.
I know that I have only recommended one brand, but they seriously make great lines. A bit pricy, but I love them.
