Curious about how tree damage plays out in the real world. I'm in the Pacific Northwest, so it will mostly be huge Douglas Firs and other big pines.

I'm trying to decide between 1.5" single layer webbing, 1/2" tubular webbing, and just the cord I'll use from hammock to tree. I'm assuming the 1.5" won't do anything to the tree. Would the other two damage it? Cut into it?
