You can do the same thing with a full ridge line.
When you wrap the tree and secure, just have the point where you secure well away from the tree instead of right against the tree. In fact when you keep the point where you secure the line further away from the tree, it is easier to secure the line whether you are using a truckers hitch, friction knot, Figure 9, whatever. This is because the further you are from the tree, the forces on the line are more in-line with the line. It's harder to tie knots when the forces on the line are pulling perpendicular to the line.
You end up with the "V" any size you want.
