I don't want to pin my setup, because it only represents my current thinking, and others might find a different setup works better for them. But right now my setup is:
Stock skis and carbides
3/8" toe-out as measured at front&rear of carbide, or 1/4" as measured in my tutorial
IFS shocks 1 turn tighter than zero preload with the sled front jacked up
front tunnel shock one half turn tighter than zero preload with the sled rear jacked up
coupler blocks on #2 and torsion springs on #1 (lightest)
This setup worked super for me in Quebec. I'm going to experiment with the coupler block on #3 and I may draw up the limiter strap too next time I ride. I like to tinker :lol:

Also, I think the clutching is just about perfect.. I wouldn't think of changing anything there.
