Ok so I joined pangea last night trying to figure out what my crestie is, they determined that he is a brindle with reverse pinning (reverse pinning is a trait and not a morph, and its the dark dorsal he has). And also just from studying morphs i've learned that he is partial pinstripe. You can see the white dashes going down his back but i don't know if it is enough to even be considered "partial pinstripe". Anyways just thought I would share.
