Well, without seeing your place it's really tough to say. I will say that hunting down at the bottoms like you describe is a real bear as far as wind currents. I don't care what's going on, down there the wind currents of a tight valley can really screw you. How much do you hunt the area. IF it's only once a week or so I'd move up ridge and find the quietest sneaky way in. The area you're hunting sounds like the deer have the wind in their favor. I'd get up top more, but that's without seeing it you understand. It's all about wind when you're in that close. If you're quiet and careful you can get in and out. I've literally had deer bedded within sight and climbed down a tree with my climber and left with them still bedded. Get the tree between you and them and you're good to go if you're quiet.
