I asked this ame question a week or two back, not many replies though. I have a Montana Elk3 , and have heard great things about them. I will be bow hunting alone this Sept , but have experianced a few times where a bull comes in to my cow calls but hangs up just out of bow range looking for the cow. I've talked to a couple archery hunters who swear by it , the bulls see the decoy and committ to coming in as long as the wind is your favor.It makes sence , so I'll be packing my decoy hoping for a chance to pull wool....I'd like to hear some other hunters thoughts on them too though..
