if you're going after pike, check if you can see some baitfish on the water. if there's abundance, change to spinner. I find it difficult to catch pike with minnow plugs when there are a lot of minnows in the water. soft plastics are good, white or green in perch pattern. vary your retrieve. i slow down my retrieve on cool temps and crank it on warmer. and of course make sure there is pike there.
