Shifting one lever inboard for up and two inboard for down (or is it the reverse) is just so dumb. Thumb shifters are much better in my vaunted opinion.
This is not a matter of limit screw or tension adjustment. I simply mean that straight out of the box, the Campy mechanisms are simply not what I would call crisp. It takes a serious throw of the finger or thumb to actuate the levers. Also, while I do on occasion use integrated shifting, I'm more partial to any friction set-up over integrated. I'm not a racer and I know that when the limit screws are set, I am going to be able to shift fluidly.
These are the only "thumb shifters" I'm down with:
