I like the Delta decoy the best. It is quite, all the legs, antlers, etc. store in the body cavity. Easy in and out. I have not tried the new Primos Scarface. I've heard mixed reviews on it. I just do not like the hard shell bodied decoys. My buddy has one of those and likes it, personal choice.
I usually use it as a buck. One other trick, only put one antler on. The bucks will attack the side without the antler, so turn it so when they come in they will present you with a shot on that side. Usually I face them away from me. I also attach an actual deer tail so that blows in the breeze a little.
You'll learn as you go what works best. It's a lot of fun!! I will not be in the woods without one most days.
