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?
when you do want to to the tip and tail, Lay the board on its side, look to see where it touches the surface. That is your contact point. Put some tape a little in front of that. Don't go past that. Take a file and go to town.
