after using a magura on mine for quite some time i think if you plan to run the stock clutch they are great!
no fade, constant pull, and are adjustable on the lever to make the pull how you want it. it also keeps the clutches adjusted properly.
if you plan to run aftermarket springs or something, it isnt worth it though. it wont pull enough to combat the springs and will probably not have enough adjustment. I ran mine after installing my tusk stuff and ran into major issues with it while trying to break in my clutch plates.
i eventually blew the seals in it after i hit the lever without having it attached and it never really worked right after that but i never wanted to get a new slave to get it working well after having issues with it.
