Dave, you must have been running the worng compound. the right compound on our enduro cars lasts 30-ish hours.
The guys in FL are Cobalt friction- I highly recommend their new line of pads (released about 18 months ago)- their first attempt was not so hot, the news are great.
We use porterfield for enduros, cobalt for sprints.
We've also had good luck with Performance friction- several of my drivers like the feel of these the best of the three.

Not so much luck with Carbotech and Hawk. carbotechs in every compound we coudl get to fit wore like a hot knife through butter. Hawk meant lots of Lockups. I haven't been able to try the new DTC line of pads, but reports from driver I trust tell me they feel and act like a Cobalt.
Not enough experience on Pagid to evaluate them.
