The question was what company makes the best skis, the fact that you don't want to destroy something that costs a lot of money is irrelevant.
Christian Bieri helped design the original Rotor 84, which is what I currently ski on.  Yes, my one complaint would be it's too heavy, which is why I was referring to next year's Rotor 84s on which the metal is thinner, and sidewalls and top sheet are more durable while also lighter (they used to use phenol and are switching to an ABS type compound that they've developed themselves), not to mention they will be true twins next season.
Obviously it's just my opinion.  If you're number one priority is light weight skis, Stockli definitely isn't for you.
