150 or 200 size Curado for steelhead and salmon.
300 size Curado if it were salmon only.
I have a Lexa HD400 that has caught a ton of yellowtail, up to 40#. Sent it in for service this year and it still looked beautiful inside. Just needed cleaned and lubed.
Caught a pile of good sized sturgeon this summer with a Lexa 400. Fantastic reel…
Tranx 500 is ridiculous. So much power in that reel. My son uses it for yellowtail because I just love the smaller Lexa.
I even use a tiny Shimano Aldebaran BFS for trout stuff because I just love not using spinning gear.
Don’t get hung up on listed drag numbers. The reel manufacturers don’t technically lie about this, but you probably won’t achieve listed drag setting with a full spool of line. In fairness, you won’t need 15# for what you have in mind. Drag setting in the “25# range” would be what I’d set up for an 80# rig…. I don’t even fish that for halibut!
