I took my 16 ft Twin Tube cat down at 2500 cfs, ran Skull to the right. My starboard oar was pinned against the wall as my starboard bow tried to climb the wall and my port stern fell into Skull hole. The twin tube cats are a little wider than a single tube cat. WW is always fun, but it's not a beginner run at any level. If things go to Hell in a Handbasket in the inner canyon, what are you going to do? A beginner might flip in Funnel, SITM, or Last Chance. Or maybe highside on Shock Rock. Filter Plant, Upper C, Ruby/Horsethief all make great beginner runs.
