To get as comfortable as I am on a Rev, I spent hundreds of hours moving the kite around the sky (all directions, orientations, with rotations, etc) at a very controlled speed in order to understand the minimal amount of input and subtle hand transitions... Again, less is more, except when it comes to practice.
