I have the mount that you are talking about, so far it has worked very well for me, I did however modify it a little. I kept noticing that there was no way to get the straps tight enough for the arm not to sag. when the arm sags and u pan from side to side everything to the left and right is shot at an angle. In other words trees look like they are growin at an angle, this drove me nuts. So i drilled a hole in the first arm put a rope through the hole, tied a knot in the bottom so it would not pull back through, and now when i set up my camera the last thing i do is take the rope, wrap it around the tree and use it to pull the arm to level. This works very well and does not take up any room or add much time to the setup.
