I got a 3-some a few years ago, and due to the hassle of messing with stakes and decoys, I just carry a hen.
One thing I did 2 seasons ago, was put better eyes in my decoy. I don't claim to have come up with the idea. Idle hands, long wait until next spring season and turkey thoughts have led to many fan-addicts to come up with the latest & greatest innovations...
I got a pair of turkey eye from a taxidermy supply shop. The next year, I saw some company selling decoys with lifelike eyes too.
My current thought on decoys are to see if I can replicate how a turkley looks in the the ultra-violet spectrum.
