The one thing to note on the Trojan -> Barnard section to keep it from getting too technical is to drop down to 13K and then contour around as indicated by the track for that section. I remember reading a TR by someone and they tried running the ridge line between Trojan and Barnard and it got pretty hairy so they dropped down to keep it class 3 or lower. From what they were saying the ridge line route is doable, but goes into class 4/5 territory, not something you'd want to lug a full pack over.
