Keep your kicking leg straight throughout the whole trick to change it into a Windex. To do this start out like you would for a Raiz. Stepover and swing your leg up straight and spot the floor. As soon as you leave the floor, your non kicking leg should follow and pump over the straight kicking leg. As soon as your pumping leg travels over, spot the target and kick through.
This trick really feels like what it is. You start like a Raiz and end it in a Cheat 720. It feels exactly like a Raiz in the beginning and then it turns over into a Cheat 720.
Alternatively you can set up like you would for the Raiz and then perform a Cheat 720 Double instead. If you take off horizontally while you do a Cheat 720 Double, it should turn into a Windex by itself.
