Roadrunners are a great go to lure for me when the action is slow on the bass...a great crappie presentation in the smaller offerings as well!
Boy...it'd almost be a toss up for me as far as the best (kinda like saying only one rifle or shotgun...

) lot depends on the quarry and conditions. it have to be down to the Rapala Shad Rap in the natural shad color and/or a white 1/2oz. sinle Colorodo bladed spinner-bait. I'd give the nod probably to the spinner-bait being that you can burn it through cover, is relatively snag-proof, and can be dressed with different tails and slow-rolled or pitched/flipped like a jig.
