IMO I would put one in the tree 40 yards off the plot. Bucks tend to hang back in cover until total darkness. With the stand further back in the timber I would think you would have a better chance arrowing a buck. Also, with you being further back, you could be able to leave your stand easier. If you're only 10 yards from the plot it might be hard getting out quietly after dark when there are still deer in the plot. Hope this helps!
