Anyone used these on the rear of a Duke?

I've been using a SC2 rear and getting on pretty well with it, (along with a SC1 front), but now need a replacement - I've been offered a good price on a SC1 rear, but how long do these last?

What's the difference in life (track) expectancy of a SC1 over an SC2?

Thanks
