I'm really struggling with tapping, and find it hard to get the rear wheel up to the edge. I want to know if anyone has any pointers on how to get a successful tapping method going, and what type of height should the wall I start on be. Also with an up to front, do you give a left stroke, then kick with the right to get the wheel over the edge, leave the ground and lean over the front to get contact with the top of the object and then wheel swap to finish.
