Sooooooooo true. At Daytona I saw pastels that I needed to read the actual sign saying they were pastels to tell the difference between them and normals.
But when I bought my pastels (a 200g insanely high yellow male and a puny little female that was pretty dull that was thrown in to the deal) and she remained kinda dull for a few months. But about a month or two ago she shed and was immediately at least as bright as my male with even better blushing! I was really surprised not to mention incredibly pleased. Now I just can't wait to make some supers with those two.
So I guess you can't always tell how they will turn out, but codoms really are being exploited and a grading system is definitely going to be needed. We as a community can help with that. If the average person looking for a spider, pastel or any other codom knew what a good one was supposed to look like and what a crap mass bred one tended to look like the problem would work it self out. If no one is buying those crappy mass produced codoms people will stop breeding them.
It is a stinky problem though, and I really don't know the best answer.
