Geez, who missed their naps today? I am no expert but organics stop well and semi-metallic stop better. Race level brakes have no bearing in my life because I don't have a race bike. I have always taken what I thought was a more direct approach. When replacing pads I usually reflect on how my brakes feel and what I would like them to do better. If I want more "bite" I get the next step up in terms of aggression. I have used aggressive pads on some bikes but it is dependent on the bike and it's purpose. With aggressive pads there is more wear but excessive brake disk wear has never been an issue for me. I have never worn out a set of brake disks in 17 years of riding and my ST alone has almost 94,000 miles. I bleed my own brakes, grease the pins, gently scrub the calipers with a toothbrush and soapy water, inspect the seals, coat the back of the pads with anti-squeak goo, and so on and so forth. Reassemble, safety check ride, and go on with life. Cheers.
