personaly i think niklas switch "dub flat" 10 is the absolute best trick i have ever seen, and i think it is just because it is on another level of shit!!! its not double to me, I look at it and I think of it more like an endless flat, you know, like doesnt leave flat and then go into a second time, but stays in the first one and makes it look absolutely amazing
so i think that particular trick should be called something other than a double. how about all time best trick ever done
