I was just looking at the same wheels. I ended up getting the Ardennes SL. The FR isnt that much lighter, and comes with titanium skewers. I couldn't justify the price difference. Arts cyclery also has the SL for $825 right now making it quite a bit cheaper than the FR or the Zipp 101. That also includes free vittoria open corsa evo slick tires and free tubes.

Mine just came today, and I havent had a chance to ride them yet.
