for me it depends on hunting pressure, deer in that area and number of days I have to hunt. If I only have 7 days and I don't see a deer until the fourth day Im takeing him/her, what ever comes in first. As long as your hunting for the right reasons (food and enjoyment)you shouldn't feel bad about any kill. Of course all of us would like to have a chance at a mature whitetail but a doe will taste just as good if not better than a tough old buck, just my 2cents.
