Too bad you never saw vids of Rolf Arness surfing backside at Bells circa '70.
Your newbie ignorance shows clearly.
Turn that video upside down , and Rolf is totally upside down .... ? .... fark , we have learnt nothing in the last 40 years ,,,,, shame on you pwa world champions , go back to school and study the insane old skool ripping totally back to the future ahead of today ....
That is not nearly the '70's World Contest waves that I saw on film.
Nor is the surfing all that great in those weak waves.
