I PMed schmies to get some answers to some of the popular questions that have been floating around the forums as of late. Here you go...straight from the horse's mouth.
True Center: +12
Core Center: +7.5
1. where is true center?
1: True center is the middle of the ski. [The Fujative] is designed to be skied in the parameters given on the side (0 - +7.5), but some of our athletes, particularily Andy Mahre are skiing it like 10cm plus.
2. does the mounting plate accomodate mounting at true center?
2: If you mount in the dead center of the ski, I think some of your binding will be off of the binding matte.
3. what is the preferred mounting postion if you are using the skis for a) park only and b) all-mountain?
3: is simply a matter of opinion. I ski mine at "core" center and like it everywhere and Andy skis his 10cm forward and loves that all mounatin. Sorry I cannot be more specific, but it really depends on what you like.
Any more questions? I'm sure he would be more than happy to help you out.
