I have two convector 30 with leadcore (8 and 10 colors). On both I used 500 feet of braid 50 pound (with 10 colors it fit perfect). Got it free from a friend. I don't recommand to use that type of line, there are less expensive line that will make the job done. Usually for salmon fishing you need about 1000 feet of line so 10 colors is 300 feet + backing.
Maybe there are guys with more experience that have better ideas.
