Two-body pion-radiating and weak decays of light axial-vector mesons and the \ensuremathρ are studied as an application of the Dyson-Schwinger equations. Models based on the rainbow-ladder truncation are capable of providing a good description, and yield the correct sign and magnitude of the a1\ensuremath→\ensuremathρ\ensuremathπ and b1\ensuremath→\ensuremathω\ensuremathπD/S ratios, with no additional mechanism necessary.
