The most basic definition of a torsion box is a construction that is contained within a full fiberglass wrap. The glass produces the "box." Keep in mind, when discussing a wood core ski (synthetic cores are a different story), the internal components of the "box" are almost always laminated together, hence the confusion around these terms...

While I do agree that many people's skis are undersized, I disagree that it primarily comes from "manufacturer marketing." It has much more to do with undercondfident shop employees wanting to err on the short side, rather than the long.
For whatever reason, PSIA has something to do with this. I've seen level 2/3 male instructors on 154 cm Supersports...beyond ridiculous, but hey, they're "opinion leaders"
Keeping the thread on track, a 191cm Mantra is still way oversized for narrowduke.
