tenex for pulling?
Jeff,
You certainly could use Tenex for pulling the tree over as it has the strength to do so, however, due to the construction of the rope itself I would say that there are better options out there.
Hollow braid ropes in general tend to "pick" more than say 16 strand arborist lines. In your example of pulling the tree over I would think that the line would become "picked" and damaged much easier when the tree crashes to the ground.
Try some double braid rigging lines or old climbing lines, they might work better for you.
