No- these were reviewed as any other items we review: we contact the company directly to review products. You are right that Komperdell manufacturers our Stix poles but that's a separate deal. I requested these poles myself and have no connection with the retail side of BackpackingLight; we keep that very separate.
At Backpacking Light we often review items that are not in the US market because of our international readership and because we're constantly searching for products that our readers might find interesting. You're right that these poles are hard to some by, as are other fine European products like Terra Nova, Rab, Lightwave, Montane, and others. I know these poles are available because I found them on several sites myself and just did the same again. Of course you could buy something that's easily available in the US but in the flat world of globally-available products and easy international shipping, you really get to pick and choose what you like.
If you decide these are the right poles for you and you track down a pair, you will certainly have something that's unique. I love gear like that, but it's certainly not for everyone.
Have a great read!
