Put me with the vastly underestimators. I knew ds6 was bright but I thought he was round 120 to 135 kind of range. 158 no that must be wrong. Ds4 though - he is probably about the same but there are some things that make me think it will be higher. Probably though they just have different strengths and ds4 has an older brother to teach him stuff (but much less input from me).
