Keith, I tried the HPS pads once-they were awful at Watkins Glen [WGI] and went through them in less than a day. I promptly went back to their HP+ and running them since. Decent compromise of street & track and seem to handle what I dish out on both with no fade and decent wear [meaning not too quickly-usually lasting my year which is 4 events at WGI, 2-3 days each event].
