Targeting muskies with walleye/bass spinning gear and 8 lb line is just plain ridiculous. Sure, you can land, catch them on tackle this light but why do it? Used to fish smallmouths, walleyes at Chautauqua some, especially in the fall, with light tackle and 8 lb mono. Caught some nice muskies doing this including a couple fat, fall 46 inchers, estimated at 25 or 26 lbs. on baby thunder sticks. It takes forever to land fish this size on light bass/walleye tackle and not good for muskies intended to be released.
Muskies definitely will take small 3 to 5 inch bass/walleye lures. My all time favorite trolling lure for Chautauqua muskies is a J-13 rapala, barely 5" long, modified with 3/0, 2/0 VMC double hooks replacing the small rings and trebles that come on the lure.
