If you go with pieces that are about 6"-8" in size, you can basically piece them together until you have an aquascape that suits you. I find that, although it tends to be a challenge to find how they "really want to fit together" - it is possible to find the magic mix with just about any kind of rock.
I'd go with rock that offers texture and surface area though. The knobbier the better.
