Hi Katie
I'm really not sure. These days I would recommend a highres (e.g. 1mm isotropic) FLAIR if you can get one, or T2 if not. The T2* can help, but it's pretty noisy in brain.

Dear Freesurfer gurus,
At the course, André van der Kouwe mentioned in his morphometry methods talk that T2* weighted contrast from MEMPRAGE could be used to further seperate dura from cortex, as also discussed in this paper: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2408694/.%C2%A0 We have a GE scanner in our lab. The internet suggests that a Multi-echo FSPGR/FGRE exists. Would this be the analog? Would it work the same way? Could you also use these images with the mris_make_surfaces command?
Thanks very much for your insight -- and I enjoyed the course!
