I managed to do this on challenge mode without using slow mo. It has to be done with the expert difficulty, Otherwise you will not get enough points. Build up and try and get top speed or at least as high as you can. Make sure you get a perfect on all the jump's and then as soon as you have done that rotate furiousley to get the perfect landing, Took me 4 attempts but i did it and did not really have a probem not using the slow mo.
