Beetlespins work, but I don't use them much to locate fish. My favorite is a roadrunner head with a small piece of worm and fish it on a hop/pause retrieve. Much more effective in my opinion. If you want to fish strictly artificial, I would still add a sweetner like a crappie nibble or berkely gulp product to it.
I like both the Beetlespins and the Roadrunner heads w/curlytail grub bodies. When using the Beetlespin, after I cast out I'll give my rod a quick solid jerk in order to get the blade spinning and slowly reel it in sometimes varying the speed or cadence of retrieves (twitch, twitch, pause... or pause, twitch, pause... etc until I find what the fish want that day). Gotta luv the Roadrunner as I've caught almost every size and species of fish that swim in freshwater on those lures...very deadly lure and just like their ad says "You can't fish'em wrong as long as you fish'em slow!!!".
IF YOU'RE FISHIN ON CREDIT, YOU'D BETTER SWITCH TO DEBIT!!!
