I got the same sled. First off let me say that I have ATTAC on my sled. It is the best thing in the world. It runs hard and crisp from here to Revelstoke and from +10 to -25. Ok now for the jets. I believe I put in 420's as It says to jet for your base altitude and -20.
I could be totally wrong on the Jets but it was for the 1500 -2000 ft and -20 range. I think it was the 420s
Anyway my point is to get the ATTAC youll never regret it.
