I was going to stay out of this thread and let the advice of veteran 'descenders' like never and scrub carry it. But then there is other 'advice' like this that really should be commented on.

The "smoothest route" is often not the "best" route in a loose, rocky descent. More often, the direct line is the best, even if that is over some obstacles. You will have more control focusing ahead (as never says) and pointing the bike straight through a section. Let the suspension (remember UK, she has full suspension) do its work. Make your route a series of point-to-point moves from one apex to the next.
