I agree with you that such a system would be beneficial for all kids. In actuality, I did not intend to make a judgment as to fairness or even relative "importance" of the different indices. It has simply been my observation that you truly need that verbal comprehension ability to appear gifted in typical GT classrooms, particularly in the elementary/early middle school years. It has also been my observation that kids who appear to have become less gifted by late middle/high school seem more likely to fall into the category of higher VC to lower (and not gifted) PR as a young child.
