i would get a bumble bee.. and breed it to your pastel.. and go for the killer bee.. but thats what im going to aim for when i start breeding lol.. cuzz thats what i like.. so im going to say what so many people say on these post.. that is choose what you like lol.. but between the morphs you have listed i would go with the mojave.. but thats again only because i like those morphs.. but you really can't go wrong with any of those..
