Smooth and steady on the big bikes - impressive. I would probably tackle those passes on a smaller bike just for that additional bit of confidence. Outstanding video👍
Looks like perfect conditions; wet but not raining! We weren’t so lucky, Corkscrew was very dry and recently graded. NOT fun. Loose dirt and rock. Especially the steep switchbacks were a real treat. At 13:00 min mark; bill was in left hand track with long sweeping blind turn; def. NOT where I would be. FWIW I think you had the correct line. Hard tell, but it seems Bill rides with little to no bend in the knees/hips/arms. Anyone else notice this?
I suspect if Bill was in what he considered to be challenging terrain he would adjust accordingly. As this was not challenging to him, he's probably just conserving energy. I do the same.
