After getting 1,000 miles on the resin pads that came with my Ultegra calipers, I decided to try the metal pads. After my first ride, I knew I'd never go back to resin pads again. I spent a lot of time to make sure they were installed correctly and centered. I have zero issues with noise and feel that my stopping power is phenomenal. I mostly ride in dry, high altitude conditions and have not tried them in the rain yet, but I'm very pleased with these pads and hope they last longer than my set of resin ones.
On my second pair of these pads and don't really have any complaints. One issue I did have was when the shop replaced my front RT-99 rotor with the cheaper RT-81 rotor. This resulted in a ton of noise and squeaks when braking. Switched back to RT-99 rotor and problems went away.
