As far as i know the outdoor has zero camber running throughout the whole deck opposed to the indoor which has rocker outside the binding holes and zero camber in between. So i guess its safe to say that the outdoor is more stable and has more pop. But what i dont get is that they are the same exact price, flex, and basically have the same bells and whistles.. What does the indoor excel at that the outdoor docent?
The difference is two boards for two different areas of snowboarding, think what kind of riding you want to be doing, and then decide. Outdoor a little more all mountain oriented, the Indoor a little more park friendly. Both are great boards.
