Fully agree with Steve, the std clutch (LUK or SACHE) is man enough
Mine was an LUK from new and did 278,000 miles at which point the cross arm that pushes the release bearing failed and killed the release bearing and then the cover plate. The spinner plate still had 0.6mm before the rivets, not to shabby when you measure the new LUK clutch and there is only 1.6mm
Im running abou 115 bhp from my tdi90 and on orig clutch at 155000 miles no prob with clutch slip.
checked the clutch about 5000 miles ago when upgrading gearbox and i was surprised as i was going to change it when apart but still loads of life left.
a lot depends on how you drive, drive sensibly and use the extra power only when needed and all is normally good.
drive like a knob and yes the clutch wont last long LOL
