My 13 F110 was having some real problems with lightness in the skis. Turned out the previous owner had cranked up the front track spring preload. After turning that down to the recommend spec it's much better but still not ideal. Going to try dropping the grant track spring preload all the way down and see how that goes, unless that's not recommended? Otherwise I might try taking some preload off the front springs and maybe eventually I'll try more aggressive carbides.
