The guy sounds like a greedy b*st*rd to me. My friend and I have several stands that we hunt together, we just alternate or flip a coin. He has killed the larger bucks more often than I, but that's just the luck of the draw. Even if you're sitting there at the same time he is if you're 400 yards away you won't be bothering him. But I agree with you not wanting him to be angry with you. I think your plan will work great, once you have established food plots the deer will come. No deer is worth a friendship, it's only a freaking deer. Good luck!
