Clevinger
I have a set but hardly use them as I really don't need them. Instead I use a small trees as a rest. The forend is cradled in my hand and my hand is against the tree.
Now, I'm not sure where you are hunting with them and I can see a point to using them. Most of my hunts are in deep wooded areas and if I were going out west, I certainly would take my set with me.
Oh, Hunting only.. ....
Be Safe !!!
