Dropped a 4.5' dbh doug-fir by 150' with an 18" bar on a small Husky. Tree was condemned from P. schweinitzii rotting bottom up, and the tree was broken off at about 12" or more diameter at 150', and rotting from the top down.
I cut the face at head high, aiming for as high as possible, hoping for more solid wood higher up the stump, and the ground on the back side was lower, so I was cutting at maximum reach on the back cut. I cut the rotten guts as much as I could through the face cut, then started the back cut in the rear progressing to one side then the other, then to the hinge on the first side, then the hinge on the second side. Pull with the bucket truck with a rope set at 55' and away it went.
The face cut side of the tree had 1" of solid rind wood, the back side had 12-15" of solid to semisolid wood. My boss had Resistographed it previously, and I drilled it with a long 1/8" bit to have an idea of what we were dealing with. Our initial intent, which did not come to pass was to break it rather than cutting it. The wood was a bit better higher up around 6.5-7' where I cut, so the tree didn't sit down, and the hinge held.
I chose the small saw because it was the lightest, cheapest saw we had in case the tree sat down on the bar and we had to unbolt the power head and leave the b/c, or if the tree crumbled, and I had to abandon the saw. Put a rut in the campground asphalt, but its a lot cheaper than a possible lawsuit. Pulled out the 460 and 660 to buck it, cutting from both sides.
Pictures are on the work camera.

Freaking amazing. Neighbor came over, "Are you doing this tree alone, isn't that kinda dangerous". "Not alone anymore sir, keep an eye on me." 
Raked and dumped chips and rolled out about 1:30ish. I've got some pics later.
