I had a big oak with a limb starting to crack and pose a danger. Some arborists push for cabling to save the tree, but others think full removal is smarter, so I installed a cable after a close look. When do you go for cabling instead of taking the branch off?
You did the right thing with that close look before cabling. Saving a major limb with cable can be worth it if the tree is healthy and the split isn't too far gone. Just keep an eye on it, because sometimes the damage is worse than it looks and removal becomes the only safe call later.
