How much does scent matter on moving baits that fish strike reflexively? Moving bait goes by, fish see's and/or hears/feels it chases bait down and pops the lure and the hook is set. Does scent matter in such a situation? I doubt it.
If you are dragging/hopping a slow moving bait along that a fish might study a bit before deciding to bite I see smell as more important. Especially something plastic like a grub, Ned rig, ect. where the bite might be subtle and the fish have the bait before the fisherman realizes it. There are some smell attractants on the market, one new one in particular that is supposed to be dynamite. Berkley Gulp, Strike King caffeine and the new Baitfuel make sense to me, WD40 not so much.
