You know what they say opinions are like A%$*&le's everyone has one, So I will share mine. I run the blues front and rear, I try not to use them often but when I do they are there. I like to trail brake and do not find it difficult to modulate them at all. I like to late brake when I need to and they are good in that department. They wear like Iron for me. I can almost get a season out of them.
I did also try the carbo's and did not like them, took to much pedal pressure to stop the car and messed up my pedal alignment on heal toe. I did not get much life out of them either.
I personally do not care what kind of dust a pad throws off, its a race car to me not a show piece, and since rotors only cost 20.00 I could care if they are hard on rotors. When I uses to track a P Car yeas ago, I was concerned about rotors when the cost me 350.00 each.
I may try the DT 60 this year at some point as I am continually trying to use as little brake as I can. I have said for awhile now, the only difference between me and my competitors who are faster is that they use less brake than I do.
This is my experience as well. Blues front and rear, never really had a reason to switch. I've driven cars with Cobalts and immediately remove them as I enjoy things like modulation and pedal length which they don't provide. I may try the DTC60/30 combo for research purposes.
