My cousin rides the Rubble. In love with it. But nothing first person. Heard rave reviews from some of my boys who have been riding the Lost Sub Driver. If the North East ever gets waves again I'm going to see about getting a few waves on it. Been on the CI Pod this past year which has been great. You can throw the tail around in 1-2 foot mush, and get a real responsive feel when driving the rail into a turn when its head high. But it does lack the speed in bigger swell. A little sluggish.
