I have the 05 scrach fs and have remounted them for a 3rd time. Once at modern, then back to standard, and the 3rd time +3cm of modern which is 4cm back from true center of the ski. true center is +7cm from modern. +3cm from modern is the best for me bc it doesnt take away from the powder and the ride on steeps but is still sick in the park and spins..plus i still get a lot of pop on the tail without losing the ability to ski the whole mountain. Hope this helps
