I would re-use it, but then again I re-used my alusils with no problems. Opinons will vary on many choices for replacing parts that have a serviceable and measureable life span.
I utilize the RCM philosophy at work and it has rubbed of on me at home. (RCM= reliability centered maintenance)
In my industry we used to do time based complete teardowns of equipment to find nothing wrong. We now use diagnostics, the number of operations and stress events to trigger this work. Parts are only replaced when they have served their useful life or have reached wear limits.

My son's '88 Toyota gets a new pressure plate with clutch soon, only because it was $65 for the kit! If we could get prices like that for our cars, then there would be no question.
