Perfect DH conditions again today, the last 3 weekends have been 

Damn, really? I tried to take a picture to explain what i mean:

Me mates just fitted a new shimano zee clutch mech and there is nigh on n difference between the clutch being on and off. The jockey wheels move just the same. Is the mech faulty or what?
Clutch mechs have nothing to do with the jockey wheels. The clutch is to stop the cage bouncing around when riding so the lower part of the chain is kept under tension and stays quieter/improves retention.
Got a clutch mech recently myself and couldn't tell you the difference between it and the standard mech I was previously running. The cage lock feature helps getting the wheel on & off though.
Forgot to add.
Unless its a SRAM clutch mech...they are a bit pants and you dont really feel the difference all that much.
