Salt Gear on the Fly

+1 on using what you have for now and just rinsing well afterwards. 

What I try to do is even if I am fish with gear, I take my fly rod just in case the conditions are right.  Sometimes it is rockfish feeding on the surface.  Othertimes when there is a large bait ball just under the surface, fly fishing has been very productive and I'm not having to fish very deep.

I have had several days that the flies way outfished the gear for rockfish.

I can testify to that.... we stopped counting at your 50th fish in the kelp if I remember right to my 4 on the crappie rig?

Fly fishing the salt off the Oregon coast is a lot different than fly fishing the flats for bonefish in Florida. Different constraints, concerns, and conditions. I would venture a guess that most people making "saltwater" recommendations aren't considering fighting toothy critters who bite in rocks in 40+ FOW.

I'm far more concerned with abrasion resistance to rocks and teeth than I am with damaging my fly line. (Cheap fly line FTW!)

No, Cap'n, this ain't no warm-water fly flinger, it's someone (not a guide) who - literally - wrote the book on fly fishing for toothy critters on the coast of Oregon.

Many (most) average fly lines are rated at 26# when they're new (if they haven't been nicked or stretched) and I find fly lines tend to be darned hard to change when I'm in my kayak    so I try keep my leaders to around 2/3rds to 3/4's of the break strength of my fly line.

Of course my leader preference is based on knowing that I'm carrying a single fly rod and if I snap a fly line, I'm done fishing for the day.
