Avoid FKS at all costs (only on this ski, I love FKS on other skis)...the core of the JP vs. Julien is not very dense at all, which is why it can be so light and so long at the same time. The FKS is the worst binding for this ski, they are the most likely to rip out and leave you kicking yourself...get the STH 12, wider Solly screw pattern, pretty burly, particularly for a 12 DIN clamp, and very light to compliment the JP's weight. Get those.
