Just did this again last weekend and I can confirm this is a stunning ride. The opening drop is just jaw-droppingly awesome - it looks slightly more than vertical when you're in the front seat looking down at the 200ft 'chasm' below you but, if you can summon up the nerve to do it, it is a terrific experience, as the ride is so fast and smooth, it is the next best thing to flying. Try the single riders queue, too, if you can - MUCH quicker than the regular line.
