I just pulled the trigger on a 2007 Orca frameset the other day and, if all goes well, it should arrive in 7-10 business days. The choice came down to either the Orca or the new Kestrel RT-700 and, while the RT-700 is a very nice frameset, the Orca is just a little stiffer. BTW, it's also .3KG lighter than the RT-700.
The stiffness issue may have something to do with the frame construction. The Orca is a true monocoque frame front to back while the RT-700 has a monocoque front triangle bonded to a CF chainstay.
I'll be installing 2004 Campy Record 10sp with Campy Eurus wheels and will post pics when I'm done.
