I'm revealing my ignorance, I'm sure, but what's wrong with braided lines like Berkley Whiplash or Power Pro? You can use something obscene like 80# test and still have a pretty thin line.

no abrasion resistance?
no stretch?
too expensive?
too visible?

I'm using it in the salt, with a snubber and mono leader. Am I just an idiot? As long as I keep it off the bottom, there's no abrasion issue. It is easy to handle, I can fit a buttload of it on the reel, and a Palomar knot seems to hold up without slipping. I'm not casting at all. Is that where the braided lines fall down?
