Lush Longboard Deck - Elevator Prog Rock 40"2012 Lush Longboards Deck Topmount with 0. 75'' of rocker for a low, comfortable foot platform, but still with the surfy powdery feel and control of a topmount. 0. 625'' Concave enough for a secure footing, but not so much that you can't move your feet around. Feel is everything and we believe we've perfected it with this rocker concave combo. Big cut outs allow super loose trucks with no fear of wheel bite Semi symmetrical shape, along similar lines
