Okay maybe I was answering a bit narrow minded on the difference in the braking force of larger diameter rotors.
The larger rotor would give you a greater threshold before you broke the traction of "said" tires. So therefore it would give better braking ability by extending the threshold of traction.
Now what I really mean is how much greater braking ability does this gained threshold offer verses the tire size's ability to hold it verses the subsequent unpsrung & rotational weight increase?
...and I'd still pick TCE's 12.2"
