Where's your spray at?
When you are riding where do you spray snow? Does it change from Blues to Blacks to Double Blacks?
A game to play to learn early edge pressure and the turns SnowWolf is talking about is to try to spray snow to the sides of the trail on a steepish Blue trail while make some short skidded turns that SnowWolf described. Try to make it so you are spraying as little snow as possible down the hill. Play with spraying alot of snow to the sides and just a little. What happens when you spray alot? A little? After you have that down, try to spray snow up the hill(very hard to do but fun to try, don't feel bad if you can't get this). After that, play with spraying in all three directions(up, to the side, and down) on a different turn. Then slowly take it to steeper and steeper terrain.
The idea behind this and early edge pressure is to start braking before you actually pick up speed. That way you aren't agressively braking at the bottom of the turn fighting to scrub speed you built up through your turn because you never gained the speed. The reason behind practicing all 3 directions is so you can apply edge pressure when and where you want it in a turn.
If you watch Pro's like Jeremy Jones riding steeps, their spray is always biggest and starts by spraying to the side of the slope rather than down it.
Good luck. Oh the above exercise is even more fun with a buddy, then you can ride side by side and try spray each other as you ride down.
