Partial wave analyses (PWA) of the 3{pi} systems in the reactions {pi}-p {yields} {pi}+{pi}-{pi}-p (the 'charged' mode) and {pi}-p {yields} {pi}-{pi}0{pi}0p (the 'neutral' mode) with an 18.3 GeV/c pion beam were performed using high statistics data from the E852 experiment. Conventional signals, such as the a1(1260), the a2(1320), and the {pi}2(1670), were found to be remarkably stable to the choice of waves included in the fit. In contrast, possible evidence for the {pi}1(1600) in the JPC = 1-+ exotic wave amplitude disappears when additional decay modes of conventional mesons (especially those of the {pi}2(1670)) are included in the PWA fit.
