I just got a new pair of Blizzard Poacher twin tips and plan to put some spare Salomon S810s I have on them. I'm trying to figure out where to mount them. The last couple pairs of skis I mounted had a single line that I lined up with, IIRC, the center mark on the boot sole. These skis have one line marked "center" and then two more lines, each about an inch further back.
I'm using the ski as an all-mountain ski. Which of these marks should I use?
