When we set out to build the Caylor, it was envisioned and produced as a pow ski that you can shred comfortably all day in bounds. For the first few runs, the flex is more supple than necessary, but after things start to get tracked out, cut up, and generally trashed, floppy pow skis aren't useful anymore. They don't plow through crud, and they don't support you when you land backseat off a cliff.
The Jeffery follows the same idea of supple flex. Based on skiing past models, the SFB is great in fresh pow, but it didn't hold up when things got chunky or at speed. In the Jeffery you'll find a ski that isn't as buttery, but can hold its own in more conditions.
