Hey,
To score good for a freestyle routine, you have to have one section of the flight smooth imac manuevers.. for example.. rollers, avalances, cuban's etc. Then after after about 2 minutes do 3d manuevers but do them as graceful as you can.. For my free routine after 2 min of imac manuevers i did a waterfall into a harrier then into a torque roll for my 3d section. Doing that got me first place for basic freestyle at the jr challenge killing the other competition by 200 points!
