The video is a good one, but at a somewhat lower level. In the 20's, Funnel gives you a wide open run on the left of that rock they pass by on the right. In fact, the rock isn't even there, but the conflicting currents and churning waves make it a place were you really need to really concentrate.
At about 4:20 in the video, you see the Skull run, with a decent look at Skull hole and what the Room of Doom is like geologically. But because it's lower, the turmoil at the Rock of Shock, and the big eddy line at the entry to the Room are not going on, like they are in the couple of pictures I posted.
