Have used quite a few decoys (Montana, Mel Dutton, plus some) and they can be really hit or miss depending on the temperature of the bucks. Had used them to get somewhere and they’re always curious but usually end up sneaking in to close the distance. The Ultimate predator decoys look sweet.
It's tough to get the smell of rutty goats out of your gear lol. Antelope are super fun to hunt and usually in areas where good glass will cut a good chunk of walking until it's time to stalk.
Hunted this same area a lot when I lived in SD, had best luck spot and stalking goats around there. They see a lot of single buck decoys which makes it tougher to decoy them in.
