The k-omega standard model should not give you any improvements compared with the SST one. Among the k-epsilon family, I advice you not to use the standard model (which is not suitable for external aerodynamics flows). Try instead the RNG or (better) the Launder-Sharma k-epsilon (but the latter needs a low y+ mesh). Try also (for high y+ computations) the Spalart-Allmaras model with nutSpalartAllmarasWallFunction for nut at the wall.
