The service went well. Wasn't cheap but Rene is the best in Cairns apparently. He reckons nothing to lose sleep over, likely a slightly warped clutch/pressure plate - hence the judder. He agrees' could be slightly glazed but his gut feeling is it's a bit buckled. The judder could be worse - he's definitely seen worse. So for now I'll just keep truckin'...

Thanks all...
Cheers
