i dunno about this one.  i'd rather have a smoother tranny than so much vert on a pipe.  that dragon looks like it'd be excessive on the vert.
pipe isn't a thing where bigger is always better too.  true, with a bigger pipe, you can go bigger; however, nobody, absolutely nobody, goes consistently big enough to require a pipe of 20 foot walls.
the problem with 20 foot walls is that you'll need higher speeds to achieve the same amount of air.  to require 20 foot walls means that you'll have to be doing 15 plus feet on nearly all your hits to make it worthwhile.  otherwise, you may as well keep you 15-20 foot walls, get the same amount of air but requiring less overall speed.
the new pipe may be nice for one hit wonders, but for overall pipe riding, i think many people, including some pros may prefer a smaller pipe.  i'd personally preder to have 18 foot pipe walls and a 23 foot quarterpipe.
