I have more jigging raps and rattling rap style lures than is healthy. I even bought some DH customs. I believe in all my time working them, I've caught two walleyes. Both came on URL on a feeding frenzy.
Otherwise I think they are good "call 'em in" lures as I seem to get lookers, but 99 percent of the time they'll swim over and grab my deadstick minnow.
When I start getting more marks, I'll switch to a standard buckshot spoon and then I'll get bit on the jigging stick and not just the deadstick.
This year I'm going to stock up on plain red hooks and splitshots. I have enough of the other stuff to last three lifetimes, and the prices of everything is ridiculous.
