Deer Decoys & tactics - advice?

[Rando]

Looking to purchase a decoy - as much to see deer reactions & behavior as to increase my (minimal) harvest rate. I'm not a trophy hunter, but antlers are cool... Just looking for advice from those that've used decoys:
- Buck vs Doe decoy which is better, when or under what circumstances?
- Best "all around" decoy buck or doe? I don't have the capital to invest in multiple decoys.
- Favorite styles (silhouette or 3D) and brands? Considering portability, functionality, and return on investment.
- Personal advice or observations on using decoys. Love 'em or hate 'em?
Thanks in advance for any input!

Don't use a doe decoy

I've used the Montana doe successfully more than once.  I'm sure the buck would work but never tried it.  I'm thinking of upgrading and I'll probably go with a full body buck.  Any doe is going to seem spooky to a decoy but that doesn't mean you won't get a shot.

I have a Montana Decoy Dreamy Doe. I've had success with it a few times over the years. I just dug it out to use in a couple weekend when I'm able to head back out again. The one thing I do is add a long white seagull feather mounted on a thin wire to add some movement as tail. It flicks with the lightest breeze. This little movement add a curiosity factor.

I have decoyed deer for many years. Always use a buck . I set the decoy up about 25 yards away from me , facing me. Be sure he is up wind of you. Bucks will circle  a decoy and get down wind of it . You want the live deer to end up 10 to 15 yards from you in between you and the decoy.

this bucks circled the decoy 3 times.
