The front to rear weight balance should not be 2/3 on the rear. I use a lot of saddle setback, with the nose of my saddle 6-7cm behind the BB center at a 73cm saddle height. Even with a lot of setback and a short torso, I have about 45% of my weight on the front wheel. Anything less than 40% is too light, IMO. The weight balance should be measured with the rider in his most agressive cornering/descending position.
Dave tell us again how many pros you have fitted since you bring them up so often?
I use a non-setback post. My STA on my current rig is 73.5. I have very small legs and smaller than normal femurs. With a setback post it feels like I'm "reaching" with my legs to make a full pedal stroke. Fitting is just like anything else.... there are a variety of opinions on the topic. Some say KOPS, some say not KOPS, and some say other things. I was fitted by someone considered to be one of the best in So Cal (and he actually has fitted pro cyclists) and he uses KOPS as a starting point. Just get fitted by someone with a good reputation and tweak if you're uncomfortable or experience displeasure. The notion to do what the pros do is so ridiculous that I'm still surprised people bring it up.
