I was finishing up the last few towers in the north while going for the Buzzsaw unlock and have found that the on foot trek to Sky Burial (759, 724), from the tower just SE of it (777, 687) is pretty much the best one I've encountered.

There are just enough grapple anchors, ledges, vines to use, but some you have to look for carefully, and once you get to the top, you're at very high altitude and can take an epic wingsuit flight. First time I did this I only hopped to the nearest tower just north, but you can easily make it most if not all the way to the farther tower to the NW on a flight that's over 1200m long.
