I just put mine on last week, so I've only managed to put about 50 KM on it. So far It's been great. Stiff, light and the prettiest crank out there.
I went from the Record aluminums and haven't noticed any difference yet.
I'm a relatively strong 185 #'s and they don't flex. The best part about going Record is the bulletproof BB, going by past records it'll outlast me. Which is more than I can say for any ISIS or Octalink BB I've used. I did manage to get 1 year out of my last ISIS, which is about triple what any other BB lasted.
I switched from DA10 to Record10 about a year ago and was a bit worried about the stiffness issues (cranks and bb) because the bike shops and mfgs seem to bring it up so often. With some reservations I went with the Record Carbon cranks and bb to keep it all Campy. Not an ounce of regret. Seems to be just as stiff and smooth plus the bb is narrower so my heels don't rub on the crank anymore.
