I've found what I think is the perfect tool for adjusting Campy (and similar) twin clamp seat posts. It's a 10mm open/box end combo, with the box end incorporating a ratcheting mechanism. I think mine was marketed by TopPeak, and I picked it up (new) at the Westminster swap last year for $2. I believe the same thing is sold by other manufacturers. Best thing I've found so far! Beats the Campy tool by mile (Italian hill country mile, that is).
