KSdan...I don't limit myself to 16" that is what the sticks are rated for. Add your 12" extension and you are up to 20", still about a foot and a half short of the trees I like to hunt from. Plus, I haven't figured out how to get it around the tree other than the first and second stick, when I can walk around the tree.. Yeah I know you can play catch, but there is always way to much junk on or around the back side of the tree. Believe me they have their limitations, and although they are not as handy, screw-ins are still more versatile, and will work in places anything that has to girdle a tree just won't get it done.
