Good advice from all. I have tried all kinds of scents over the past 15+ years and have had mixed responses to all. I have gone from trying to do elaborate scent drags and circling the stand to just hanging some quality estrous scent right at my tree/blind or none at all. All that other monkey business just prolongs your time on the ground and spreads more human scent/noise. I usually buy one small bottle of something like Wildlife Research select golden estrus, Code Blue standing doe, or Tank's estrus. I agree with the Tink's 69 business, it must work some but so many people use it, I avoid it. I have used it and noticed no results good or bad.
You have a great block of time to hunt and if you spend a lot of time in the field you will see it all. Chasing, breeding, cruising, noting, all of it. Stick with it and try to minimize their knowledge of your presence. If you have a lot of bucks in your area and a good buck/doe ratio, rattling can work. If the herd is sparse or lots of does per buck, rattling will likely be less effective. With that said, if you are going to try, stick with it. One day you may get zero response, and the next you might have 3-4 bucks running over each other to get there.
For antlers, I have a medium size 4x4 set that I use and think they sound fine, but if you are using antlers worth rattling with they are bulky and annoying to pack. I have handled the black rack synthetics and think they sound great, and have seen guys have amazing success with rattle bags as well.
For calls, as hokey as they are, I've had the most dramatic responses from the Primos can call. I've had bucks come running right to the base of the tree. For a grunt call, there are a lot of gimmicks out there now with snort wheeze, roars, etc, but I still like a plain old grunt tube with an adjustable band. After selling them retail and using lots for years I have stuck with my Rod Benson grunt call. Nothing fancy and probably cheap (haven't looked at any in a long time). It makes the most realistic grunt I have been able to get out of any grunt tube, but I'm sure there are calls that have come along in the 10+ years I've had mine that are as good or better. I agree with what's been said about just making simple grunts at the right time, which is all you need.
With all that said. Overall, I think with the time period you will be hunting, you will be well served to scout and find funnels and pinch points that bucks will be cruising and don't worry about calls/scents/rattling. If you can locate feeding and bedding areas for the does in the area, and locate some decent bucks and where they travel; find a way to get in their travel path without them knowing you are hunting them, and just watch the show. When I got very serious about minimizing human activity at my hunting locations and being religious about playing the wind, is when I started seeing mature deer. They are there, but if they know you are, you will never see them (except during the peak chase). If you can find three, four or five different travel corridors/funnels (for different winds), and hunt those tactfully, you will do far better than setting up in a good looking area and pulling all the tricks out of the bag.
Whitetails are creatures of habit, and outside the rut you can almost set your watch to them. For the time of your hunt, get on the does, pattern them, don't let you know you're there, and wait. Also, if you can, sit all day. I have seen some of the biggest bucks and my friends have killed many of their biggest between 11am and 2pm. Does are in beds, bucks are cruising from one area to the next, and other hunters are walking back in moving deer around or are back at camp. During the chase and post rut there is no dead time. I've hunted days where I could only be out from 9am to 2pm. I've seen nothing, and I've seen 5 bucks.
Have fun, use the skills you have and keep us posted!
