You guys are discussing the issue that I have had for years with twin tips. Ubfortunately because so many of the under 30 crowd are getting airborne and landing switch (even sometimes when they can hardly ski) tiwn tips are becoming a bit of a necessity for ski companies. They just don't wnat to rule out some growing percentage of the buying public. Since none of us needs them we end up having to go much larger in actual size than we would need with a flat tailed ski (as the running length shortens a lot with twin tips). You end up carry the extra weight and length but you actually get no benefit from it with regard to stability (running length is what makes a ski more stable at speed with regard to fore aft balance). I still love hardtails especially on powder skis. They are so much more confidence inspiring in the steeps, in chutes and in tight spots as I can feel my tail pretty much anytime I want by getting back slightly and I can dial in my exact fore aft position from this constant feedback.
With the advent of the terrain park, twin tips are here to stay and they have quickly become standard on all big mountain, freeride skis. But if you watch Jeremy Nobis or Scot Schmidt or a few others with a racing background (guys that don't land switch but will do super G turns in steeps at mach schnell speeds) they are all skiing with hardtails.
Having said all this, there are some awesome twin tipped skis, and we are for the most part convinced that the chariots are in that category!!
