in the purest form, being done how they're meant to be done, they are really smooth and add a lot of style to a trick.
that being said, in the 10/11 season they will be all over the place and will turn out to be poorly executed reverts that make kids look like they can't do a simple 2sev out but have to wash around their spins. don't get me wrong, i won't even attempt them because my rail game isn't anywhere near that level. i appreciate what hornbeck is doing and am only hoping that the masses that try to imitate him won't make the trick into something less than it deserves to be.
