I rode my brothers "x" for a day and found it to be an extremely fun board. Fast, stable and very poppy. That being said, I have been riding for over twenty years, in all kinds of conditions.
It was still a deck that was capable of scaring me, if you do not ride it like you mean it, it will toss you, and you will not get the most out of it.
Like one guy said....its a board you KNOW you want, if you question it, prob don't need/want that one!
