BoulderMtNutwrote a review of Burton Custom X Snowboard on March 8, 2013
This board is not for beginners or really even intermediate riders. If you don't have the strength or experience of a seasoned rider then this board will buck you and bring you down hard and fast. Even if you manage to stay on your feet it will tire you out. So if you are thinking of this as your first board I recommend the regular Custom (rocker or camber).
That said this board is amazing, I ride pretty aggressively and this board has never let me down, not to mention it's built like a tank. This board just wants to go fast and turn hard, and the more you give it the more it holds a carve. Even the wide version is lighting fast from edge to edge. I take it to the resorts and backcountry and it's at home in both. It's a little on the heavy side but that doesn't bother me. If you like a stiff and fast setup this should be the only board you are considering.
