The natual selection post got me thinkin. When I dump a tree I like to notch and cut at a comfortable height. Usually about waist high. Once the tree is on the ground I can then get 2 rounds cut from the stump. The reason for this is that I've seen and had things go wrong enough that if and when they do I aint all bent over with my butt in the air. I see these guys on vids walk up to a tree and bend over till their almost standing on their heads. Kinda looks like it would make for a slow getaway if you had 1 that wanted to twist and shout iffn you know what I mean. Maybe I'm just to cautious but I aint been kilt yet. It would be different if I was cutting saw logs I s'pose.
