The one at 7:50 I can usually clean with pedal position and slightly unloading the front wheel to point it through the hole. The third section at 8:25, I've never been able to clean due to that big ass boulder around waist height. Carrying speed through some of them helps as well since you are reacting rather than over thinking your moves. I have a good friend that lives in Leasburg and rides there often. He knows those trails far better than I do since I only get to ride them when I visit.
