Ya but the problem is, they aren't "frosted" at all, there is no weakening of color in the middle of the saddles. I have no problem with there being a dividing line, but I just don't like people saying all Cinders have high saddle count just because I hatched a few that do. I've hatched over 150 animals from these lines over the years and have come up with 5 high count animals. I just happened to like it and saved them back to be tested, especially since they are also Cinders. I don't get the high counts in normals, nor most the Cinders.
Separate yourself for a minute and think about the logic....
If you hatched 150 Amels from the same lines and 5 of them had a certian "different look", would that be enough for your animals to need to be marked as something different?
Honestly, I like the different pattern and would love to start a line with a proven heritable trait like that. I really do hope it's something I can reproduce again. In the meantime, I think it's silly that people are for separating a line because it has 5 odd balls out of over 150. If you look that hard you'll find a reason to suspect hybrid in anything.
