Im heading up north of Kenora, Ontario on the English River system on Friday. Been going up there for 15 years. Always have used 8 lb test, recently converting to P-Line Fluorocarbon. Never needed anymore than 8 lb, we troll and drift with half oz. jig heads tipped with minnow or leech. As for Pike go with 15 lb. whatever with a steel leader. Pike fishing is crazy up there, every cast. Ive heard the smallmouth could be spawning up there or have just finished. Dont for get the smallmouth goodies.
