Some use braid, some use nylon monofilament. I haven’t heard a lot about fluorocarbon line out in the bay. I like fluorocarbon leader. I like braid, 30 or 40 pound, with a fluorocarbon leader something like 20 or 25 pound stuff.
I don’t think any line or rod or reel, unless it’s a complete piece of junk, will keep you from catching fish. You get where you can find the fish, your set up sounds fine to me.
