Shimano Dura Ace BR-7900 Road Bike Brake

We've been accused of over-interpreting things in the past, and maybe that's exactly what we're doing here. Bear with us, please, and allow us to start with a question: Has anyone here ever had a headache of note with a set of Dura-Ace brakes, regardless of the generation Sure, we remember the 7700-series brakes that came with terrible pads back in the Michele Bartoli-era and we all upgraded to salmon-colored Kool Stop pads to achieve better stopping power. But except for that one now-forgotten incident, would we all agree that Dura-Ace brakes are pretty much phenomenal In our minds, this isn't controversial stuff.What's interesting, then, is the fact that the folks over at Ciamillo Components who manufacture the ultra-lightweight Zero Gravity brake calipers seem to have a bit of a bullseye on Dura-Ace. Visit their site here and find the page titled "Powercam". On this page they make an argument that Zero Gravity brakes are superior because as you pull more brake cable they provide intensified braking power. By virtue of this argument, they suggest that Dura-Ace brakes are inferior because they provide equal braking power no matter how much cable you're pulling.We're not engineers. We're bike racers. So the first time we read this page we asked ourselves whether predictability is a good thing. When we're buzzing down the road at 30mph in the middle of a 60-man field, fighting for wheels, tapping our brakes -- is this a circumstance where we're aware on a moment-to-moment basis of what Zero Gravity calls "% of pull/arm travel" Maybe we should be, but we're not. Our experience is this: Whether we're touching the brakes or grabbing them, we want to know how much stopping power to anticipate. We don't have time for slide rules and quadratic equations, and we certainly can't define at any given moment whether we're at 20% or 60% of our allowable lever pull. Without this info, Zero Gravity suggests, we can't properly anticipate how much stopping power we'll experience.
