Looking forward to your post on Limerock...

Thanks, Vince
XP12 has more bite, but I didn't have trouble modulating it. You would be fine with either I think. I got XP12s mainly because of the temperature issues I was having at the Glen; they can operate at higher temps than the XP10s. Measuring rotor temps and having an objective sense of where things are might help you make the choice. HT10s I used at the Glen scored both rotors deeply in several locations. After a day with the XP12s, those grooves are smoothed out, so they can grind things down. Although the wear with XP12s is even, which is a good thing, it is somewhat visible after one track day. So, I guess that is the trade-off between a more aggresive pad like the XP12 and RS19/XP10 (fade resistance and bite vs rotor wear). My 2 cents...I know there are other people on this forum who have used XP12s, so maybe they can chime in as well.
