You gain more height going in reverse as your rear wheels add double the traction before the boost hence you can hold down more power. The rotations themselves happen without any real imput. In fact you dont have a choice in the rotation, a harder aerial would be trying to do a reverse straight jump.
Its an epic feeling, with no room for error, I come from a kite surfing/windsurfing background there is no trial and error on land, no suspension and no water to land on your head, you have to get it right each and every time.
I am going to start replacing the Mantas with Flysurfer Speed II's the Flysurfers are the next level, last weekend at Lake George I was able to pull some technical moves on the Flysurfer I usually opt out of on the Manta, the difference being the Flysurfer points so much higher into the wind allowing for rotations under the kite much easier.
And the float....... nothing comes close
