Sweet! It looks like you slipped that over your log back stop? Aren't you worried about bending that? I would be! Its nice how high your cable is but it doesn't need to be. It just adds to the forces on your back stop.
I would cut down your post so the cable just clears the far rail when going over the log at the bottom of the ramps. That would reduce the bending moment on the back stop by 1/2 to 2/3.
