I try to find the sweet spot so the coil can easily be flexed by pushing it on the ground for when I want to change the angle, like for reaching under playground equipment, or hunting on a slope, even stowing in the car, I fold the coil up a bit..... I've put some little plastic washers made out of a plastic milk jug or something similar between the coil ears and the shaft...with a pair of scissors and a paper hole punch you can make them up quickly and add as many as you need (between the coil ears and the shaft)...they allow you to set the tension on the coil bolt to what you like for your coil to be firm, but still have a little give..thin rubber washers work too, but they grip so tight, they dont allow a smooth coil transition when a guy wants to change the angle of it.....also taping the coil wire to the shaft 6" above the coil keeps everything somewhat right...every once in a while, like once per week, a guy has to reach down and tighten the coil bolt since it has a way of working itself loose because of changing the coil angle all the time...a little loose is probably better than too tight...cant have it flopping, but dont want it too stiff....
