With Toyota LUC dual-mass flywheels you never know. It might looks great when you visually inspect its friction surface, but internally it might have stretched springs and/or damaged rubber dampeners. Trust me, you are better off installing a new one in there, for the peace fo mind. Especially if you are installing it together with a performance cutch. They are expensive, but when installed properly they last a long time. Replace flywheel bolts too, of if reusing old ones coat their threads with Loctite so they dont back out on you. Hope this helps.
