These are the lines I've used this year.
SA Streamer express, is hands down the best integrated shooting head line but lacks a little in the toughness category due to the mono core. It'll always have a place in my bag though.
SA Wet Tip express, has a braided core but it isn't as cast friendly as the streamer express. It's still a great line that'll last several seasons.
Orvis depth charge, much like the wet tip express but a little tougher, you can't tear it up. Down side is no color code, its all orange and brown.
SA Ultra 4, IMO the best deal on a floating fly line out there. You can usually get it cheap, it has the AST coating, it floats well what else do you need.
Sage Equator, good stuff. I got mine when STP clearanced it out. I should have bought a lot more. It’s a great line in any weather with a nice fat floating taper.
Wonderline, despite to poor reviews I’ve had good luck with the stuff. I’ve had to send a few back but Orvis always made it right.
Rio Gold, had to send one back but the new one seems to be 100% better. Nice line and cast’s great. I’d buy it again.
