The standard definition of "still hunting" is actually sneaking along quietly and slowly in search of game. In this scenario I would not use any scent, unless you believe in cover-scents and wouldn't use a call because that would give my location away.
One method I have heard of repeatedly, but have never done personally, is to drag some sort of scent rag when you are still hunting in the hopes that a buck may pick up the scent and start following... hopefully right up to you!
