I know this is a blacktail thread, but I have hunted the early mz for mule deer the last two years and have loved it. In scouting, I've been able to pretty much pattern the bucks because they are for the most part still in the summer feeding patterns. I don't know much about blacktails, but I thought I heard that they are more patternable than mule deer. If you put the time in and scout, you can basically get an excellent opportunity to get the first crack at the deer in the fall because not too many people archery hunt early.
