I'd go with nothing before something. Whenever I put out scent, I've seen various reactions - from curiosity to terror! Check out what is walking in the area if you haven't already. After a couple of sittings, give the double drag a try, a couple grunts wouldn't hurt, but go easy on them. Then go full blown scents, grunts & rattle.
The idea here is that you don't always know if and when the big boy is coming out. You may not need anything for him to show. A lot of times when you hang scents out, you won't see a thing because the does avoid them and at this time of year, you want the "real deal" in the area.
By the way, I don't recommend hanging scent bombs at night because you have to go retrieve them in the dark and may come face to face with your big buck. He won't appreciate your presence and will learn quickly that he is being deceived/hunted. I did this the other night and spooked two deer (of unknown sex/size) that were only 30 yards from my stand. Personally, I am going back to scentless for a couple of days.
I am still skeptical (but hopeful) of scents and rattling/grunting. They have to be used with the right wind, at the right time and when grunting/rattling - performed correctly. If they are not, they can screw things up. Additionally, they require you to create movement and tromp around in the shooting lane or field. Be sure to wear rubber boots and descent yourself when using.
Good luck.
