We ran it on Saturday as a day trip as all but 9 of the 20+ opted out because of weather/flows. Four hours from the ranger station to Cisco. Fast water! Pretty much everything was washed out. A hole was forming on RR in surprise. The lateral on skull was big. Seeing the carnage in The Room before dropping in makes you think. That boat is trashed! Needed to keep pulling much longer than at lower flows to miss the rock of shock. SITM didn't pack its punch.
I think the biggest thing is knowing where you are. Lines are the same, but mistakes could happen because it is all flying by. Things that are defined at lower flow merge together. A few in our gang couldn't believe we were done when we rounded the corner below LC. A swim would be unpleasant and dangerous.
There is a great new camp with hot springs that we never knew about... they call it 'Super 8'.
