The ridgeline will bear 100% of the load when the suspension is pulled to horizontal. So there is literally no limit to what you can put on it. BTW, when the suspension is horizontal, the load is infinite.
Don't play with Mother Nature. Keep those angles some where within several degrees of 30*.
Many hang without a ridgeline. They can eyeball a 30* angle from 100 paces; they got skills!
But then again, I need a place to hang my spectacles at night.
