Replying to SPK vs. Ghost FS 90 vs. Ghost 110

Salomon stopped making the SPK. Fuck.

Now they make a Ghost FS 90, which they say is modeled after the SPK. They also make a Ghost 110, which I also know nothing about. I currently ride 27.5 SPK 100s (317mm BSL), FKS on all my skis, would like to avoid remounting at all costs.

Is the BSL, last, and forward lean still the same as the old SPK...?

What is the difference between the Ghost 90 and 110? Just the stiffness...?

Halp!
