The trick to the rattletrap is learning how to work it. You could just cast and retrieve, and you will catch some fish, but if you want to maximize your luck it takes a little more finesse. I like to use a medium-action 6.5" rod with a flexible tip. Cast past cover, and retrieve quickly but twitch and pause every few seconds. It will take some practice to get to where you can do this without getting the line wrapped around the front treble hook. If you can master the technique, bass can't resist and will slam the lure on the pause. You will tend to catch a lot of smaller fish with this lure, but it works very well.
If you are trolling around, and you see a big school of white bass in a feeding frenzy, cast this lure past the school, and use the same technique. You will catch a fish on every cast. White bass are fun to catch, they fight like crazy, and they taste great, too.If you go fishing a lot, don't get too attached to this lure -- it works in Spring. Just when I thought that I never needed to buy another lure, it stopped working. I couldn't get a bite. Time to fall back to worm fishing. I have always found that when all else fails, tie on a worm and fish it slow. You will catch a few fish, and they will probably be bigger to boot.
