Have a look at my photo album from last weekend. When I sent David the link to my photos, his reply was that "you take a photo about every 50'.
About all I can say is that the route stays on the south side where past where you would normally head across to the E-ledges. Farther up, generally, you would tend toward the north side, but whoever put up the current route kept it well to the south side and it ends up on the plateau above, and south, of LBSL.
Again, it's easy to see what I'm talking about if you look at the photo album.
