A better understanding of the energy loss of partons in the quark-gluon plasma formed in the collisions of heavy ions can be gained by varying the collision system. Recent RHIC runs have provided Cu+Au and U+U collisions. Asymmetric Cu+Au collisions provide a system with similar energy density but different path lengths when compared to Au+Au with the same number of nucleon-nucleon collisions. Also, in the most central Cu+Au events the surface bias is reduced in the Cu-going direction. Similarly the non-spherical nuclear U+U collisions can produce different energy density and surface biases compared to Au+Au collisions. In this talk we present the results from $\pi^0$ and $\eta$ production in large systems. We discuss comparisons with Au+Au and how those comparisons further our understanding of parton energy loss in a quark-gluon plasma.
