I use rub lines to let me know a buck is using the area and they can sometimes tell you direction of travel but I rarely will hunt a rub line unless I think it is a stagng area where some bucks are hanging out right before dark before going out into the cut corn or alfalfa fields to feed. Staging areas will be somewhere between the bedding areas and the feeding areas and will not have any pattern of direction for the rubs to be in but there will be a lot of them all around in one small area just off of a field or some type of feeding area. If you know where they're bedding and where they're feeding youmay want to get back a ways from the feeding areas and between the bedding areasbecause many times they won't get to the feeding areas until dark unless you can find a good active staging area. When they start rutting they will abandon all rub lines, scrapes and feeding patterns and you will have to hunt where the does are if you want to find the bucks.
