How often have u caught these bucks on camera? I once read that mature bucks very rarely if ever use the "deer highways". They mostly move and stay under the cover of heavy brush. If i was going to try to shoot one of these monster bucks i would place a stand somewhere that u can find a "back entrance" to the food plot. Heavycover or maybe pines is deffinatly your best option. Get in your stand at least 45 min before leagal shooting hours and stay all day (or as long as possible). If he has grown to be as big as you say he is then he will not enter the plot till after sundown and he will leave the plot before sunup. Chances are you will only get one shot at your buck so practice hard and make it count!

Also you will deffinatly want 2 or 3 different ways to get to your stand and enter on the path to the stand that will be best depending on wind condition.

Good Luck!
