Just one other note on sub-d smoothing - if you do want to take the output from MoI and produce subdivision from it, you'll generally need to use a retopologizing tool to reform the polygon structure to make it suitable for that.

Try topogun or 3D-coat for that.

Those generally still require some user interaction to make a nice topology but they have a lot of tools set up to make it go pretty quickly.
