I'm no pro but I read in one of the 50 or so fishings mags that I subscribe to recently an article were the guy was talking about rattle spoons and the great success he was having wally fishing thru the ice. So much so that he tried an experiment where he glued some rattles to one of his regular spoons....great success also....then the rattles fell off and the success continued, he then came up with the conclusion that it wasn't the rattles so much as the action he was imposing on them to activate the rattles, that was resulting in his success......just thought I'd throw that in there
