If you're serious about the buck hunting, I wouldn't do a thing, but rely on the natural patterns of the deer. Your intrusions there will not be tolerated by a mature buck. You may blow him out once, but doubt he'll want to stick around if you intrude on him more than that.
It's a bedding area for a few reasons. It offers security, maybe is out of the wind and is convenient in reference to the food. If you go intruding in that area, they will no longer feel safe and find a new spot.
To simplify it, find a spot between the bedding and feeding area and ambush them in the later part of the day when they leave their beds to feed. For a morning, hunt, do similar. Ambush them on their way back to their beds. Keep in mind, mature bucks have a tendency to leave the food source before the other deer to bed... and are one of the last ones to enter open feed sources in the evening. That's why it's also a good strategy to set up a stand somewhere before they reach the food source.
Since you already witnessed deer coming from an area, leave well enough alone and set up based on that. No need to try and make it better with the corn and urine. Bank your hours and you'll connect eventually.
