One thing about the open face notch, Bill, if you use it within the tree on vertical logs, your going to send the piece into a real big tumble and spin and possibly plant it into the ground or when it hits the deck it's gunna jump around like a bloody lizards dropped tail.
I like using it when you've got a scaffold limb hanging just out over the fence and you don't want to rig it, that way it swings and then folds all the way back into the yard and sits down nice and horizontaly.
