The way I look at it is this:
If I have a dinker male, I breed it to a normal female to try to prove it.
If I get a dinker female, I breed it to a morph.
Look what happened when someone was like "Oh, this female looks neat...let's breed a mojave to it" and POW...Crystal.
Or "this one looks interesting...I'll breed it to a yellowbelly" and pow...super stripes.
One dude even proved his OWN line of Crystals AFTER the originals just from dinking. (Lucky SOB)
So yeah...dinkers can be fun.
