[UW-GIS-L] Geographic Transformation for NAD 1983 --> Sphere Mercator?

[JEFFREY S. LINN]

I'm trying to convert a few feature classes from the City of Seattle standard projection into something that can be displayed in Google Maps. The ArcGIS project tool won't let me project the data without a proper geographic transformation, but I have no idea which one I should be using.

I'd imagine that some of you out there have done this before. I'd appreciate any advice you may have.
