Most of my walleye come from shorline fishing. I cast from shore for 'eyes in the fall at some of my local reservoirs, but do not do much in the river during spring run. Our rivers get pretty crowded. In still water and lakes i have caught them on big/bulky sculpin tied jigs and bucktail patterns but i opt for a head shape that doesn't cut through the water so easily. Fall fishing in cold water means a slow retrieve and i want to keep jigs up and out of the rocks. Flat bottom jig heads or even simple round heads i feel let you move a little slower than flat vertical styles. Again, i am casting from shore mainly and fight with the rocks constantly.
If using plastics....... 4" curly tails or 4" swim baits rule. If all else fails, husky jerks and other stickbaits are heard to beat.
