If you go up to the SEARCH menu and type in Decoys it will give you tons of information relating to past questions related to this. I have been using decoys off and on for the past 20 years and have settled on using 2 hens and a small jake placed about 15 to 20 yards from my setup. I would avoid the shinier models. Decoys arnt necessary alot of the time, maybe even most of the time. But there are some situations where having them can make the difference. I use them in field situations.
