i found that cutting the top out with the Humboldt notch and a back cut level with the face cut leaving a small hinge leaves less abrubtly than the traditional felling techniques.
Good job, grass hopper.
I do not use a humbolt up in a tree very much, but some times it has its advantages.
The big wide open face cut and the big hinge some people use can cause a big ride.
What happens is, as the weight of the top moves the direction of the fall it pushes the uncut tree in the opposite direction (one reason the back cut should be slightly higher than the face), then as the face closes it pulls the part you are attached to along with it until the hinge breaks. The hinge breaking suddenly releases the tree and can cause a pretty violent action in the remaining tree.
Another good one is cutting a lot of weight of a horizontal or leaning limb. and having it snap up as the load is suddenly released.
Ummm............. Most modern techniques are not very traditional.
