There's more than one way to wrap a flip line.
360 degrees...goes from your right D around the right side of the tree, continues around to come back towards you on the left side of the tree, continues left to right in front of you to go on around the tree from right to left again, the back to your left side D. This is super secure, but sucks the hairy moose lips to move up or down the tree.
270 degrees is easier by far to flip up or down, and just as secure imo...from your right side D, goes to the left in front of you, then on around the back of the tree from left to right, on back across in front of you from right to left, to attach at your left D.
