I want a translation of surfer dude...that sounded fun!

Well, sir, you get the best shaped waves. The tube shape is optimal for experiencing the thrill of being in the barrel of the wave, after which you exit the the barrel... It's as such: you come over the top and you use the momentum to swerve back up near the crest again and then drop down the face of the wave allowing the barrel of the wave to form over you... you can come over the top of the crest and get in the pit of the wave, right there... It's a fantastic experience.
