I think you have two different deer here. Both impressive, and would look best staining my tailgate. I don't know much about scoring deer, but the general shape of the beams is diferent, and the split brow tine on the black and white lead me to think they are different deer. However, there are some serious experts on here, who will most likely make me eat crow, but that is my opinion.
The only real difference between a good tracker and a bad tracker is observation. All the same data is present for both. The rest is understanding what you are seeing.
