Unless they'll be used exclusively in deep snow, I'd put the pin holes on your boots at the middle of the running length of the ski. take a string and hold it both at the tip of the ski and at the point where the tail of the ski makes contact with the snow. Fold the string in half, and this should tell you where the pinline ought to go for the most versatile setup. This might make the bindings look too far forward, but since 3 or 4 cm's of the tail of the ski have no bearing on the way the skis run, it will
I just had a pair of big daddies mounted with R8's, and the shop guy went ahead and mounted them at CC. This is at least a centimeter behind the center of the running length of the ski, and although it ought to be even better in deep snow, I have a harder time engaging the tip of the ski on harder surfaces than I would if the binding was on the true center of the ski.
I'm not a ski tech, and i've only begun to ponder these things recently, but I think i'm on the right track. Ask someone like Eric O.
Uh, christopher, that mount would be a powder only mount. It's ball of foot on running length center, not pins on running length center for all-mountain general-purpose. That would put the ball of foot ~5cm behind RLC for me- maybe OK for powder but sub-optimal on hardpack.

It's important to be careful with terminology when various center measurements come up.
"Chord center" (CC) is half the distance from tip to tail, nothing else.
"Center of running surface" (CRS) is half the distance from where the tip leaves the snow surface to where the tail leaves the snow surface.
"Running Length Chord Center" (RLC) is when you measure chord center but you ignore the tail of the ski after the point where it rises from the snow surface.
Typical/traditional telemark mounting in the U.S. for years was pinline at CC. More progressive mounting, especially for firm-snow use, has been closer to ball-of-foot on CRS. A compromise between the two, frequently satisfying to users of twin tips in a broad range of snow conditions, is pinline at RLC.
I think it's possible that dana took christopher3000 to be talking about pins-on-CRS when he actually meant pins-on-RLC.
