Best selection of cuts to save out 60" dbh Cedar advice

[slabMan]

I have a 162' Western Red Cedar tree that is 79" at the stump and 60" dbh. The only place I can fall the tree is into a 8' tall berm made of fill dirt. I want to drop her as softly as possible to prevent damage to the tree. I have her chained/strapped together just above where I will make my backcut to hopefully prevent any fracturing on impact. What is the preferred undercut, hinge, and backcut to set her down as softly as possible? The tree has a natural lean in the berm direction, so perhaps a shallow face with a fat hinge or some cuts to allow her to hang on as long as possible? What say the experts?

In for interest.

So am I..... I would soften the landing with loose straw or hay however, especially of you plan on using the wood for something.

Unfortunately, the berm is rounded and 8' tall and for a large 2nd growth that is above avg in height, straw won't do it justice. I was going to pull the tree down with my 980 wheel loader, but those roots are really in the ground and I am afraid I would snap the tree at the 50' anchor point in a "triple line pull with offset anchor and 3:1 ma". Cutting the tree will give me more control anyway. I thought of a "gapped" [aka orig. Humboldt] with a chunk of the undercut used as a fulcrum [snipe?] to get the tree to roll about 1/2 way into its fall and onto the limb heavy side of the tree as a cushion. That is probably what I will do if the big brain AS experts don't have a better suggestion. I might try and post a vid or pics if need be.
