But you can make an asphalt gravel if you really wanted to. Although they are really nice, I think it's better to keep them separate lines because super gravel or super asphalt are both just as nice and i fear if people continue to mix them, eventually the line will be blurred and they may not continue to be their individual morph. It is obvious to me that they are quite different but i think they are close enough that by mixing them we will eventually get to the point that people are selling them as the same morph. I personally like asphalt quite a bit better so i will continue to work with it exclusively. My suggestion would be to pick whichever you like better and stick to making the super form mixed with whatever other morphs you like, there is still tons to be done with them without needing to mix them.
