On this board, there's only been one US Scura clutch/flywheel failure, and it was not a catastrophic failure (serial number S288). Maybe best to look for a US Scura with a serial number as close to S600 as you can find? Re: other bikes, word on the street is that the valving/springing of the Ohlins of the LeMans Corsa, Coppa Italia, and Cafe Sport models was closer to the mark than on the Scura. If you would rather go with one of those, note that the LeMans has clip-on bars, whereas the Coppa Italia and Cafe Sport have riser bars-- so depending on what type of riding position you need, you might want to consider that. Of course, you can always mod the bars to suit your needs.
