The nature of coronal mass ejection precursor magnetic structure and eruption triggers has implications for the properties of the erupting CME, including its mass, size, velocity, and topology; properties which in turn affect the CMEs evolution in the solar wind and ultimate space weather impact at 1 AU. We present forward-modeled coronal, heliospheric, and in-situ manifestations of the CME, and discuss how such observations may constrain models of CME triggers and improve space-weather predictive capability. In particular, we draw upon the recently completed Data-Optimized-ICME-Modeling database of thousands of simulated CMEs propagating and evolving in the solar wind, which is based on the combined Wang-Sheeley-Arge (ADAPT), Gibson-Low, and Gamera models. This database offers a powerful new means of studying the correlation between different CME characteristics and an avenue for deeper study of the physical causes of these correlations.
