Mark Mandic (Markus Jayne) produces some super pastels he calls super duper. I don't know if he's isolated a gene or its just a line breeding of some REALLY nice supers. I'm guessing that's what the original poster was asking about.
you are correct, i was refering to Mr. Mandics super duper pastel - should've explained myself a bit better
got a male duper (direct from Mark) here, and have put him to a pastel fader
wasn't sure if the fader gene would show itself in the offspring
