I have a bench on one of my ridges, but its a high bench. High enough to catch the wind right. This bench is surrounded by beds. I hunt it early in the morning with a south wind and catch them coming back to bed or during the rut when bucks are scent-checking the bedding area. And when the sun comes up the thermals really pull my scent uphill well. The reason it works though is the fact the bench is only about 30 feet below the ridge top vertically.
