Haha, sorry I didn't explain that well. No, falling leaf kills all momentum. I'm saying rip a toeside, spin 180, rip another toeside, all at speed. So, finish the toeside turn normally, start the edge change normally, but instead of setting the heelside edge, you spin the board 180 and set the toeside edge.
For a goofy, the toeside-to-toeside 180 spin is clockwise (viewed from above). For a regular, counter-clockwise.
