Replying to Progression

hey guys so ive only really been skiing for about a year now and its fucking great. nothing is more fun that sliding around the park. i can ski slide with both feet forward on flat rails and boxes and even some DFD boxes and stuff like that and im looking to progress. should i be trying to 270 on or off first? also i have the irrational fear of sliding any rails that arent flat. can somebody give me some advice/motivation to help me really start throwing down?
