Hey, my mountains having a big air event in a few weeks. Any advise on what i should do for it. My hill (and town) is pretty small and last years winner did a 9. The jumps about a 30 footer and right now im capable of spinning 5. Should i learn sw. 5 or 7? but a grab in? (obviously but i wont be able to spin as much) if so what one looks good.
