Soft plastic leeches will definitely work for walleye. When the bite is going strong, many anglers will switch over to soft plastic for walleye. You can keep it simple with a jighead or a drop shot rig and a soft plastic leech. Vertical jigging on the bottom is very effective for walleye or you can fish the leech on a spinner rig. Try casting or trolling with the spinner rig and soft plastic leech and you should have some success.
