shaky head

[twigass]

i have read and heard alot about this and i personally have never tried it, but am wanting to try it. my question is how do you rig it and how is it used. i have a few heads that they call shaky heads but just cant muster enough to try it during a tournament. i live in northern Michigan and the lakes i fish mainly have alot of cabbage weed and submerged timber and stuff. so i guess if any1 can tell me how to rig it or send me pics or even a link to try to watch it done would be greatly appreciated, also what type of worms do u through on it
