If you're talking about putting spinner blades on in place of baits without hooks ..... I'd say it depends on what you're looking for. If you're looking for flash, a willow leaf blade gives off more flash than other blades. A smooth finish gives off a brighter flash, a hammered finish gives off a less bright flash, but a larger profiled flash. Willow leafs also spin more tightly so they have less lift than the same size blade of another style. Less lift will let the bait run deeper. They also produce less vibration than other types of blades.
Colorado blades produce more lift and more vibration, but less flash. They're good for stained water because of their vibration. The added lift a Colorado provides will help keep the rig higher in the water column. Indiana blades are kind of a hybrid of a willow leaf and a Colorado blade. Mid level lift, mid level flash, and mid level vibration.
As far as configuration..... I'd rig it as if you were basically just throwing a big multi armed spinner bait. You want the flash above the body.
