The Custom is one of the most ridden boards in the industry. The deck is a tried and true product from Burton. This year Burton is offering the Custom with a Flying V core profile not V-rocker.
Flying V has V-rocker between your stance, camber underneath your bindings along with frostbite, then rocker on the tip/tail sections. All the ingredients to give you the best ride possible.
The lighting bolts are there to increase response and give you more board feel, and the Channel is the greatest system to allow the most fluid flex of a board possible. Grip it and Rip it.
