Good to hear there are examples of easy going cinni gene snakes. My exposure is very limited. I've seen one super and he's a terror and then I picked my male from two brothers and didn't pick the nicer looking one because he was the most aggressive ball python I've ever seen. The one I did pick is rigid when handled but doesn't actually strike.

I have seen aggression follow family lines in other projects so maybe it's just that some of the founder cinnamon's or some of the early normals they where crossed with where aggressive animals but it's a separate gene from the cinnamon mutation?
