Have confidence. The Factory Direct Demo. Buy a pair of DPS boards. Get them mounted right when you receive them. If you don't think they are the highest performing boards you have felt beneath your feet, ship them back within 3 days of receiving them, and assuming you haven't done any nasty rock damage, get a full refund, minus shipping costs both ways.
Sorry, we can only offer Factory DIrect Demo to North American customers at this time.
