If you're taking out more than the lightning tree you could cripple it up and drive it with another tree.
If you're taking just the one fall it the regular way but stay on your toes. Watch your chips...big color changes, punk dust, that sort of thing. Sounding the tree might not be a bad idea either.
More pictures, especially the first third of the tree from the ground, would help.
This is my first thought too, cut it the regular way . #### like that can sit on your bar just when facing it making things all of a sudden far more dicey than deisred but other times they just go over like anything else. Make sure your laces arte tied and tucked out of the way. But, I do try to have my face and hinge somewhat on the perpindicular side to the fracture if I can in somehting like that so that the tension is not running parallel to the fracture thus lessening the potential for enhancing stresses on fracture while felling- ya?. Seems to make sense in my mind.
