I've seen it a few times now. Good surfers that by a firewire potato thingy and then temporarily become kooks while they get used to it. Was a dude at the beach the other day that normally rips but was reduced to struggling to even time standing up correctly. Quite a few trips down the face on his knees. Was pretty funny. Every now and again he'd time it right and rip the bag out of the wave....only to return to kooksdim the wave after. Am tempted to potato up (they look so fun to surf) but I am already to much of a kook!
