ok heres my shot, so i belive the fire and sulfer are just like a cinnamon and black pastel, they look basiclly the same with minor differences but noticeable at the same time, they both make basically the same super. yet when breed to other morphs you can also see the difference, like a black pewter and cinamon pewter look different, just the same as a sulpher pastel and fire pastel look differnt, i personaly like the fire pastel better just like i like the cinnamon pewter better too. so diffrerent morphs but close to the same results, i think it really comes down to what people perfer when it comes to other morph crosses with the fire and sulpher, i perfer the fire and the cinnamon crosses , get it
