I am taking my new 09/10 K2 Apache Crossfires with Marker Mx 12 integrated bindings to my local ski shop this weekend to have the bindings mounted, skis waxed etc. I was looking at the bindings and they adjust for boot length in 10mm intervals. My boots are 358mm long which is between binding length intervals of 355mm and 365mm.
Does anyone know if which setting I should ask the shop to install the bindings at? Is there any advantage to rounding up vs rounding down? Based on how the binding seems to lock to the rails it looks like rounding up would move the boot further forward on the ski... and I am not sure if this is desirable for an intermediate skier still learning to carve?
358 is closer to 355 than 365 so am I correct in assuming the 355 setting would put the boot closest to the 'ideal' center of the ski?
Also is it bad if the shop adjusts the forward tension screw on the back of the binding with the boot clipped in?
I am sure the shop will have an opinion on the subject when I take the skis in but I would like to proactively educate myself aa bit first :)
Any help is appreciated.
