'Given that these forks are the best on the market'
According to who? Even pro Fox MBR have been complaining about the latest offerings. Choose between supple and excessive fork dive or harsh ride and restricted travel. Worn CSU's seem to be a common complaint. 32mm versions are flexy compared to the competition. No reliability testing appears to be done by Fox, it's left to the customer and the service centres to sort out under warranty.
'Which forks are you running on your bikes?'
Rockshox. Minimal maintenence. Fantastic reliability. Well over 2000 miles with nothing but lower oil changes. Never had a leak, never changed a seal.
Unfortunately my Trek Rumblefish 29er came with a F120 RLC. It's been to Mojo 3 times and still doesn't perform as well as my older Revelation forks.
