I would not worry so much about the rub line. Maybe give it one hunt during rut. I would bounce around and hunt close to bedding, once it gets down to the last few days of October or after nov.1st start hunting pinch points, leeward ricges, etc... But keep moving, if your pounding that rubline with scent hunting and setting/checking cameras every buck worth hunting will smell your scent there and avoid the area in daylight...
