The best place is actually two places or more depending on how many head configurations you have. It is best to find the balance point for each head type. As for steaks, you can make them yourself from several different things. Old alluminum arrow shafts work well. They have the tapered end for nocks that will fit right into the holes in the dekes. Woodeb dow rods would work if you have a way to taper then ends. Those are you two best options of you can't find any in stores. As for putting them in the gorund. That depends on the wind. Light winds they should sit higher so they get the range of motion. Windy days its better to keep them on or close to the ground so they don't blow off. Good luck and happy hunting.
