I'd probably set up in the cover.
My advice is NOT to set up in the cover. It is very difficult to place a decoy where deer will see it and also a deer standing dead still, decoy, in cover especially thick cover, is an ALARM to other deer. Deer react in many ways to a decoy, in the wide open, they generally at least come look at it, although they do ignore it at times. Every single time I have placed a decoy in cover, every single deer that did see it, spooked and quickly.
I have killed several does when using a decoy as a doe. Does hate an "unknown" doe showing up. They will check out a doe decoy quickly and they focus on it. Not really, but it seems like you could go jumping jacks and they wouldn't notice you.
I believe a decoy that is a buck is best for bucks. Several bucks have came to a buck decoy for me, just nothing I wanted to kill.
The hardest part is placing the decoy so deer can see it. It is crazy to put a decoy out and think most any deer that comes by can see it, but my biggest issue has been deer I can see from the stand but they never see the decoy. The deer needs to see the decoy for it to attract them and it is hard to get a decoy where they can be easily seen by the deer.
