Belden attributed the difference in CMRR to certain colors being microscopicly different in diameter, thus affecting the mutual coupling in the twist.The differnce was on the order of 2dB or so (IIRC), and the best they could twist the pair at that time was on the order of 66dB.
I don't generally freak out about balance/unbalanced, it doesn't matter in practice. Unbalanced with an input transformer outperforms electronically balanced, period.
