I think they should dfinetly be part of your hunting tactic arsenal. I wouldn't hunt with it all the time. I have hunted for about 33 years and I have had a decoy for about 5 years. I hunt wikt it probably 5 or 6 days a season. The 2 most memorable hunts I've ever had have come with the decoy. I use a Flambeau Redi doe. I think they have the best coloring and very realistic. They are more brown, the color deer are when they get their winter coat, so of the others are more red like deers summer coat. Buck or doe.....I don't know.... I just know I have really good success lots of shot opportunities on does and bucks, even had the decoy mounted twice and had it rammed and flung 20 feet by a huge buck. If you hunt the same area most of the time, the deer will figure it out, usually the mature does. Thats why I suggest not hunting all the time with it. I was thinking about getting the Flambeau Buck for this season and mix it up a bit.
Good Luck!
