Just to wage a little war....lol
I got 10,000 out of my first pair of Metz on the rear (factory) and went with Bridgestone... I've only got 20,000 miles on the bike and already have replaced the bridgestone and about 1/2 way though my second one... However, I would say I've become more comfortable on the bike for the second 10,000 miles than I was the first
