Lightening and lightening bug my good man..  an inherently balanced  
engine means that by it's design it is less susceptible to vibrations  
about an axis while a performance balanced engine has to do with  
dynamically balancing all of the rotating engine bits to minimize  
their effect on vibration by matching static weights of components and  
matching those to the offsetting rotating components.  it allows,  
theoretically, a higher max speed with less chance of a particular  
component failing.
