The Carruthers faced almost all the challenges of other brother/sister pairs, but I think they're a slight exception to the general guideline that it's difficult for brother/sister pairs to excel at the senior level, because they're genetically unrelated. However, they weren't deliberately matched up like most genetically-unrelated pairs, so as with most brother-sister pairs, there was a significant amount of luck involved their adult sizes being appropriate for pairs. [And for all of the criticism leveled at the Hartsells, I'm more impressed with their accomplishments as the years go by: they may have been the only genetically-related pair who won medals at the Senior level with adult bodies in the triple twist era. (Does anyone know if Melissa and Mark Militano did a triple twist? I know that she did one with Johnny Johns, but I'm not sure if the Militanos did one.)]
