Rangerdangers tree wasn't all that bad. Looks like a typical included bark fork tear out. No rot there, though lower down looks a little suspect???
Its the dose that makes the poison. Small sections with low impact rigging seem to fit the bill from the armchair : ) Lots of room to build a cushion with the brash to dump the trunk wood.
Some things look worse than they are and vice versa. I had a job recently that had very heavy timber ontop of brittle decay at the base. Looked sound in the last 3 foot until you cut a disc and pressed the center to watch it disintegrate. A shell of about 1" thick sound wood. That was it on 30" DBH of Oak. An old decayed fungus body (Laetiporus sulphureus) and very poor woundwood alerted me to the danger. Turned out quite complex with the rigging, which made for some interesting pics and vid.
I should stress that IMO, 'cut and hope' and false bravado scenarios are a recipe for disaster with extreme trees. A well developed sixth sense and respect for the unknown are still required after the scientific absolutes and contingencies are considered.
If I can get in a crane, I get in a crane. If I can't get in a crane, its priced and prepared for accordingly - steady, surely, catchy monkey...
If I don't get the job I breathe a sigh of relief and pray for those that do.
