I know some of the old timers used to put a single salmon hook on the back of spoons and sticks. The idea was that most the time the walleye will keep whacking at it until they get it... However the worm on the spoon idea I am not to sure about as it's going to mess up the action of the spoon. If you want to run meat..use harnesses or something else that's of inline configuration. Not something that has to have it's back end flopping around.
Good luck....
