Actually, no, the rubber failing is a LOT more common than the metal failing on a harmonic balancer. Matter of fact, the only times I've seen the metal fail is after the rubber lets go and the outer section does a rapid departure at high engine speeds.
Consider that the strut mount isn't subjected to petrochemicals, high engine heat, and spinning at up to 5,000 RPM routinely ...
And that there was probably more rubber in the strut mount than in the harmonic balancer.
Let's not forget the main difference between a "race" balancer and a "street" balancer is the rubber compound used.
