Go with HPS, I run HPS on my Fozzy, and I run HP+ on my Rex, and I tell you HP+ on stock rotors, is the worst misteak of my life! Worst noise ever, once these rotors or pads becomes shot(which ever comes first) I am going stock rotors and HPS like on my fozzy! I am very pleased with the stopping power of the breaks. I live on a huge hill and my wife rides the hell out of the breaks and over 2 months so far on that and they look brand new still when we r almost about to change her breaks out at the 3 month mark!!
