A simple partial wave amplitude analysis of {bar {ital p}}{ital p}{r_arrow}{pi}{sup {minus}}{pi}{sup +} has been performed for data in the range {ital p}{sub lab}= 360{endash}1000 MeV/{ital c}, where remarkably few partial waves are required to fit the data. Furthermore, the number of required {ital J} values does not change in this energy range. However, the resulting set of partial wave amplitudes is not unique. We discuss possible measurements with polarized beam and target which will severely restrict and help resolve the present analysis ambiguities. New data from the reaction {bar {ital p}}{ital p}{r_arrow}{pi}{sup 0}{pi}{sup 0} alone are insufficient for that purpose. {copyright} {ital 1996 The American Physical Society.}
