Replying to Mounting Question - Reference Points

I just got 06/07 Scratch FS WRS skis and i'm going to be mounting them soon

Last year I rode K2 PE's at core center and I wanted to mount them at the same place on these new skis.

We all know K2 has funky measuring and reference points for mounting, so do you know what would be the equivelant of the K2 core center mounting point on my new Scratches?  Please specify if you are giving me the + __ measurement from the "standard" or "modern" line.  Thanks guys.
