My tarp currently has paracord that was supplied by the manufacturer and I was wondering if I should use it alone or in conjunction with huggers when hanging from trees.

Huggers would make the whole system heavier but a) I don't want to damage the trees and b) The added friction of Huggers may help prevent the tarp lines from slipping.

Do you use tree huggers when you pitch your tarp? What is your rational for doing so? (damage/slipping/something else?)
