I bought two boxes of their premium almost two years ago, and the rock goes in both directions. Yes, I got the softball size pieces. But I also received some nice larger pieces. The softballs were the dense ones while the larger pieces were nice with lots of holes and crevices throughout. Depending upon the size of your tank it can either be perfect or a pain. In my 125 it loaded it full but was difficult to aquascape. In my 240 it is great as building supports in the rear as well as good coral placement pieces higher up.
