Good Vid, I learnt some really useful points regarding slings.
Again though, proper use of a tree as a rest wasn't fully covered. In my opinion the best way to use a tree is as follows: A right handed shooter shoots on the right side of the tree - this gives visual cover by breaking your body outline and allows a really solid rest. Ok so for RH shooter - With left forearm at 45 degrees to the barrel and a death grip on the fore end, both elbows up, push the back of the wrist hard into the tree trunk with right leg back and straight, push like Richie McCaw locking a scrum. This gives a solid positive hold and imo is vastly better than the finger tip tree truck tickling position off the left side of the tree.
