Haven't noticed the standard P2K brakes to be a problem but Ultegra is definately an upgrade.

Again, wondering the difference between Ultegra pads on the DiaCompe brakes or just new Ultegra set. I have definitely found that the current brake setup has less stopping power and response on descents....I live in NoCal and the only way I get a ride that isn't hilly as hell is to drive out to Stockton and ride there.

Cervelo braking actually isn't a problem until next month as I don't need brakes on the Computrainer :)

The newer brake arches are a lot stiffer than our old model, so presuming that is what you are noticing, changing the pads will not give you the change you're looking for.
