I feel a good angler should use line/rod and reel combos like a good golfer uses dif. clubs! With that being said – here are my preferences with lines:
Trilene XT 14 to 17 for bass and big walleye cranks (Salmo #6 Hornets and DT-6 through DT-16) spooled on a baitcaster – lighter cranks – XT 10.
Trilene XL 8 on a spinning rod – when you need to cast smaller cranks like a #4 or #5 Hornet, Flicker Shad or Shad Rap. I prefer mono over superline 80% of the time because of the stretch (Less fish come “unbuttoned”).
Fireline 14lb – On a spinning reel – when you really need to get the crank back (IE Devils Lake, Mississippi River wood, Etc) IF Northerns or clear water become a factor – 20 pound Fluro Leader – 3 to 6 feet in length.
Berkley Nano Fill 10 lb – when you really need to chuck a light crank a LLLLLOOOOOOONNNNNNGGGGGG ways. Careful not to “overcast” to avoid ending up in the “salad” on shore.
