Spinnerbaits can be used for anything. I was on balsam Sunday, fishing weedlines away from shore and managed pike in the double digits, a few musky, perch and bluegill (surprised me) and 4 walleye over the slot (all released, don't keep or eat fish). Only one OOS brute smallie.
When its a cloudy day with some or little chop, spinnerbaits are my favourite lures for walleye, same with lipless cranks. They just flat out catch them.
