It works best to space out from the bottom up with the lines. This spreads out the patches more consistantly, but it extends the length of the snuffed spin. Most socks are pre-set for the supplied spin patch spacing, so you have to do it like on Mark's. If you are setting up the system from scratch, or have an extra long sock, go opposite.

Also watch going to too small of a halyard line. On the Superwing masts, we found that when we had a 4mm line and after a windy day where we ran max down haul, small bits of the halyard line slipped out of the mast groove. These bits of stangled line made it impossible to get the main down without flipping the boat and pulling it out by hand. We run 5mm now and it has not happened since.
