I use this http://www.woodswise.com/details.php?pid=ww087and this http://www.woodswise.com/details.php?pid=ww088. All I do is night hunt. This area isnt really made for day calling.
As far as decoy, I would think it would be pointless but I may be wrong. I did knowa guy that would find and kill a rabbit then cut into it and everywhere they walked where they would hunt they dragged it with a string on his leg. It REALLY helped.
