Don't know if it will "help", but I doubt it will "hurt". I've seen people vertical jig a Roadrunner & catch fish !! (& they were only moving the bait a couple of inches up/down)
IMHO ... if you're using a Roadrunner, and you're not retrieving it fast enough to make the blade spin, then you're really just using a high priced "jig" But, that's just me.
