I was interested to hear about the other pad options, thanks Invader. Those who have "upgraded" to the EBC double-H pads, myself included, have noticed better performance (more initial bite, better feel), but I haven't heard much about warp (rotors?). Perhaps this phenomenon is more common to racers, where repeated heavy brake application can lead to heat build-up.
I also upgraded the lines to SS braided and change the fluid regularly. I bought the cheap ones (Bremzen). My lever is firm with modulated two-finger braking over a 1/2" span, with another 1/4" for extreme measures. Unless you are set-up to work on brakes, have the shop do the SS lines. You need to push (or pull) fluid up through the lines, and you'll fight it for a week without a proper setup.
