So to summarise:
- Don't worry about touching the edges until(if) you discover a need to.
- Don't worry about the tip and tail, though it won't do any harm if you want the kill half an hour. Just be careful not to go far past the contact points, you can't put the material back on.
That's a pretty solid board and binding combo, you should progress fast on it. Where in the alps are you going to be?
