If I had pro level control over my skis I would do:
Slide the whole rail but gap the last down with a front 2 (or 6 if you're nuts)
Urban entry disaster to the top of the first down, front swap over the last kink, land switch
Urban entry disaster to the top of the first down, front 2 out gapping the last down
front swap the first kink to down, continuing 2/4/6 out gapping the last down
Lip slide the whole rail and tail press the last down, come out switch
Front swap the first kink to down and then front swap the second kink, land on the very bottom of the rail and come out switch
If I really wanted to be gangsta I would slide the flat at the top and try to gap to the last down and come out forward
You could also alley oop disaster 4 to the last down and come out switch
