Being the absolutely cheapest and laziest hunter in Texas, I went with the easiest decoy I could come up with:
Tip end from 2 piece fishing rod (about 3 ft long)
turkey feathers (one turkey will give enough for years)
short length of fishing line
Tie 1 to 4 turkey feathers to top ferrule of fishing pole with slip knots so you can easily remove them to go to next stand, stick butt of pole in ground at a distance appropriate for calling type (i.e close to stand if mouth calling, close to caller if electronic calling). Sit back and watch all kinds of wildlife check out decoy. I have even had deer and/or cattle come up to it and smell it. Extremely light weight, works in any weather, low cost, natural colors, easily replaceable, requires no trees or brush, etc, etc.
I put a small piece of velcro on the fishing rod so it can stick to my shooting sticks or backpack.
The only down side I have found is this year the grass, weeds and other ground cover has grown to ridiculous heights from the extra foot of rain we have had in west Texas. I had to dig around in the shop to find the other piece of the fishing rod so my feathers would be tall enough to be seen over the flora. Thankfully, it was a 6 1/2 ft rod. Works out to clear everything except the sunflowers after removing shaft from grip. Well, there is one other problem with it - I have lost one of these to a red-tail hawk who took the whole darn thing. He dropped it after about 100 yds, but I never found it.
