[NSRCA-discussion] Avalanche - Positive or Negative Snap?

[Ken Thompson]

I again stand corrected.  My thought was that the snap should be to the 
outside of the loop to control the amount of drop that the model will 
encounter, being in the stalled position.  I don't recall judging anyone 
that did a positive snap, but I certainly see Arch's point.

This is why Archie flies the way he does, and I fly the way I do <BG>
