My take on your land Foggy is this, the guys said your camp was able to kill 3 nice bucks off of 120 acres in MN,.......in one year......did I mention your in MN? With that success, means you have already done a lot of things right. We could tell you to start doing this or that project, but you may not have anymore success than what you already have had!
But if you do want to do want to do a few things, expand some of the nice plots you have and try some corn and beans, and do those right with all the proper fertilizer so you get tonnage. Then inner seed some Brassicas during the summer for even more tonnage.
Move some stands off of your food plots if possible, if not, no big deal, but I think moving stands a little would help improve some of your hunts.
You have deer moving on and off your farm, and deer randomly moving about your farm, and the random movement is the same problem most of us have. For me the tornado effect of hinge cutting the piss out of some good areas you already have in and close to the center of your property would increase the holding capacity of deer and keep them away from all the deer stands your neighbors have surrounding your land. That coupled with the expansion of some Corn/Bean Plots, may bring you some hunting improvement!
Just my take on a sweet property! And once again thanks for letting us on your land!
