  Encouraged by the latest SNO results, we consider the lepton mixing matrix in
the approximation that the nu_2 mass eigenstate is trimaximally
(democratically) mixed. This suggests a new parameterization of the remaining
mixing degrees of freedom, which eschews mixing angles, dealing instead,
directly with the complex parameter U_e3 of the mixing matrix. Unitarity
triangles then take a particularly simple form, which we hope will faciltate
comparison with experiment.
