I haven't skied the touring models, but on the Atris, Orb and Navis I can say this:
Atris: playful, stable and versatile. Not too heavy, but not a light weight by modern (AT) standards. Wood core + fiberglass only, tip and tail rocker, step down sidewall. Serves a huge range of skiers and conditions with a very versatile 108 mm underfoot.
Orb: resort ski, damper than the Atris and with 88-90 mm underfoot much more hardpack-oriented. Float was a bit dissapointing compared to other models in that range (Blizzard Brahma, Völkl Kendo), but very stable, powerfull and damp. Not too lively though.
Navis: in between, literally (102 mm underfoot). Very much like the Blizzard Rustler 10. Very stable, good hard snow performance too, not too much tail rcker (if you can call it even that). Lighter and more playfull than - say - Nordica Enforcer 100, but much more sturdy than - let's say - Salomon QST series.
