I didn't ask to take any pictures of the two outbred sibling supers I saw but one of them definitely had some nose problems along with the kinks. I don't know how common it is but the ones people are more willing to post photos of are probably the ones with little to no problem. The other one looked good to me but like I said the breeder thought it looked a little off too. I suppose the way to get to the bottom of the less obvious defects would be with some actual caliper measurements maybe of ratio of nose width to head length or something like that and see how it varies between normal, cinnamon/black pastel, and super cinnamon/black pastel siblings. I wouldn't expect a small amount of duckbilling to be a big deal but it sounds like some of the more extreme examples and the kinked ones are a possibility you need to consider when breeding for supers.
