Welcome to the Forum.
I learned to fly quads on a Rev 2 - also not the easiest to learn on. Remember that it only takes tiny wrist movements for inputs. It's easy to over-steer with too large of inputs when one hits panic mode while learning. It helps to set-up the lines to the pigtails with as much brake as possible and still able to move forward, in order to slow the kite closer to brain-speed. My difficulty was using too much speed for everything while learning, since the Rev 2 was my high-wind kite when it was too windy for dual line tricking. Once I started flying the Rev 2 in lighter winds and at slower speeds, the learning curve was a lot easier to overcome.
Best advice that helped me was to pick a spot off in the distance such as a cloud, tree top, or building and try to slowly rotate each direction while keeping the center of the kite in the same spot. That helps develop muscle memory and small inputs. Inverted hover was hardest for me. I was told to slowly add input until the kite just barely lifted off the ground a foot or so and try to maintain that position.
The Supersonic is awesome at flying backwards and inverted side slides. Have fun and good luck.
