We are attempting to reproject several raster and vector datasets from GCS_GRS_1980 to WGS_1984_Web_Mercator_Auxiliary_Sphere.  I have tried a several different transformations but each time there is a noticeable shift in the data.  Does anyone know the correct transformation to use?  Our data is mostly in the SE United States, mainly Georgia, South Carolina, & North Carolina.  We also have a few datasets that span the entire USA.

I'm having the same problem determining the correct transformation from state plane (GA FT, SC Int FT, & NC FT) to web mercator.  Any ideas?

Thank you very much in advance!
