Taming S4RS Clutch

At 6000 miles my S4RS clutch basket is toast - started to get whiny, grabby & grindy. I've popped a pic up of the basket - I'm thinking of using it as a cheese grater. I've also added an Oberon slave &, as an experiment, removed two clutch springs. I now have a delightfully light & smooth clutch & gearbox. I'm curious if anyone else has run an S4RS with 4 springs successfully & if anyone can tell me what problems I might expect? I owe an apology to Ducati Glasgow BTW, as I was didn't believe the basket could be wrecked at so few miles - mine must have been made from butter. Sorry for incredulous response guys.
