Rub line, by far. scrapes are mostly visiited nocturnally. a rub line is a buck's travel route. thats where he's going to travel. they dont visit scrapes consistenly enough to get a buck over them. just because they make it doesnt mean they're going come back to freshen. and the chance they will in daylight hours is even less. rub lines connect the bedding area to a feeding area usually. easy choice. most of what is written about scrapes isn't very good information.
