My standards have come a long ways since I started out. From shooting any buck that walked by to holding out on a good one for my area, meaning I judge him to be 120+ or 3.5+. My standards on does hasn't really changed. In most areas I'll shoot any non young of the year doe, with a tendency to pick the biggest of any group coming thru. In special regs areas, and expecially if I am on the ground hunting, I'll shoot any doe, even a small one. They butcher up fast and are mighty tasty, and there are a lot of deer.

As far as game plans go I head into a season with the general strategy of shooting does early and often, unless I think I can pick off a mature buck the 1st couple days. THen its all low pressure doe hunting. Once the last week of Oct rolls around does get passed if I still have tags left. Then its all about the big boys. Although I can't speak for my actions atthe moment of truth, I don't expect to lower my standards on a buck late in the season.
I also try and plan out the next few days hunts as I go thru a season. However I try to remain flexible for things that pop up.
