Maybe I'm mistaken, as I'm really not a huge coasterhead or anything. The few hyper and gigas that I've ridden are generally just variations on the same glide-y experience. I don't really believe that adding another 200 ft to a coaster will change that very much at all. It's maybe a few seconds difference during a drop at those speeds.
It'd be neat to see something like this built somewhere else, but I'm not losing sleep over not riding this myself.
