I gotta agree with you. I think desert ghost ages better than any other gene in terms of retaining and actually increasing brightness. This is especially apparent when combined with pastel. DG leads to a complete 180 in the aging process of pastels, where instead of browning out they just keep getting more and more yellow.
Here's a quick pic of my Pastel DG male who is almost 1500g and about 4 years old.
