I don't specifically use that name. I have never been much fond of the Amelanistic cultivars that have been variously labeled as "no-whites", and now apparently called "SunGlows". However I do find it interesting that the SunGlow Motleys seem to have originated from a line of Amel Motleys I worked with for a number of years. I've been working hard to get more contrast into them, however, so that original line doesn't live here any longer.
I tend to like high contrast animals, for the most part. In those cultivars that tend to resist this appearance, I try like heck to make them that way. Heck, if I can't do this stuff to please myself, why bother doing it?
Anyway, sorry I can't help you out with those.
