I agree with the buck weight being a factor, but I think deer are like humans and we all look different. Especially after running the girls hard. One of my biggest bucks in east tx was one of my lightest too. He was just a small looking deer. I dragged him by the handle bars for 300 yards in the ice and took only one break. Ive killed some in the same area that I couldn't drag 10 yrds without falling down and bitchen. an extra 75 to 100 pounds makes a huge difference when dragging a deer. And as for the doe question, it was a good one. I factored it into my survey. Not a lot of does get killed by hunters in my area, but the cars do a number on them. The cars kill more does and young bucks than I could ever think about surveying.
Sometimes you just have to hold back. The odds are stacked against me and him. Then you see him in mid Febuary with full head gear and the glory hits you. Next season will be wanted even more.
