Not sure if you have the means, but the sport has progressed so much with training tools. If you can, hit woodward. Foam pits, training tools, trampoline with spotting belts etc. Give you air awareness and the ability to feel the trick out while greatly minimizing the potential for a hospital visit. For rails, build a box out of wood and carpet top and get used to spinning onto and locking on to the 'rail.' Of course doing it down a 15 step is going to be different but knowing the movements and balance points will make it easier.
