IceTech rotors (RT81/86/98) are a bitch to straighten 'cos of the alloy rotor ring (which is steel-coated for wear resistance on the faces). It doesn't have the springiness of steel, so they just end up getting kinked & stuffed. I've buggered one up after inflicting a not-that-severe bend in a stack.
