Thanks guys - that buck was actually the fourth on my hit list. I got close to my #2 several times but the shot just never developed. #1 was either poached or shot I think as I have not seen him since August. He was a beautiful eight that would have went in the 160s. I also had a 170 inch buck close in Ohio but never felt comfortable with the shot he presented - he'll still be there next year as he survived the winter.
Back to original question. One other thing I did this year that made ALL the difference was to listen to John E. I used to reach up as high as I could to tie in. That was uncomfortable at best and had me swinging around the tree. I moved to an eye level hook up and a system that lets slack easily come into my strap so I can rotate it easily around the tree. I use an Ameristep T screw on back side to keep my strap/rope from sliding down the tree during the slack phase while I am walking around tree as needed.
What this did for me was it made it far more comfortable as I sit, easier to stand for a shot, and so much easier to walk around a tree. I also now can easily cross my feet over (facing away from tree trunk) for those dreaded right side of tree shots.
I also went to a minimalist modified saddle that allows far more freedom in shooting positions.
The most important thing you can do in my humble opinion to avoid getting busted is to not let the deer know you are hunting them. I paid a lot of attention to entry and exit routes and I never over-hunted the stands I had set up. I also did (and I am currently doing) all my stand set-ups in early SPRING (valuable lesson once again taught by John E).
There are times no matter what you do you will get picked off - that's hunting. When it happens I try to ask why it happened and then try to make adjustments. Personally, I am glad deer hunting is not 100% - but then again I like a good chess match
