Mr_pretzelAnyone ski both of these and can compare them? Also where did you end up mounting?
I've only spent a bit of time on the regular ARV 106 but the main differences seemed to come down to stiffness, damping, and swing weight. The Ti version feels a bit stiffer, is a bit smoother on rough snow, and requires a bit more effort to swing around in the air. So the more you care about stability, the more sense the Ti version makes. The more you care about freestyle performance, the more I'd recommend the standard version. They were both really fun skis and pretty versatile, just some subtle differences.
And I don't spin a ton and like to drive the front of my skis a bit, so I ended up liking the 188 cm ARV 106 and 106Ti with the bindings at around -5. I liked the 180 cm ARV 106Ti better at recommended around -2 just cause I thought I didn't get a whole lot out of that ski by mounting back and wanted to maximize playfulness instead.
