EBC green stuff are hopeless for the track. Don't like the feel, feels very dull and doesn't pull up well. I had Endless NA-M and also same thing, but worse cause of more $ I paid for it.
RB74's are great. Takes a very long time to make them fade and their cheap too. Very good initial bite, gives you very good confidence in your brakes.
However the best I've used are Comp 9's from Racebrakes. Same as RB74's, but can take more punishment (no fade what so ever after 4 or 5 punishing laps at Eastern Creek) and bite more. However they didn't last as long as the RB74's, and made more noise. Also harder on rotors. But I don't think you'd care too much as performance counts.
