NWBoarder is right. Snowboarding is so mcuh fun cos there is no real stress in progression. As long as u have fun on the slopes, you go home everyday feeling like a winner. Feel free to entirely ignore this post but my 2 cents are:
a) You MAY WISH to avoid going down the path of going for sheer scale (40 Footers) because all you need is more speed (which is easy, just point it) instead of developing some technical skills to complement it.
b) You MAY WISH to add some more variation by going from 180s to 360s on Flatground. Bring your Flatground 180s to small jumps. Learn to tail and nose press, back and front board onto jibs (all the basic tricks really).
c) You MAY WISH to do everything you already can, but switch.
