Rick, whatever doc you decide upon, make sure he can do megasessions/dense packing in one procedure (that's 2k grafts and upwards), especially with your NW level. IMO, while the coalition docs are all good and do ultra-refined work, not all of them are showing megasession numbers. Perhaps their sites are outdated, and I could be wrong. Here's who I considered for an HT:
Feller (who I went with--all around great doc)
H&W (show very large numbers for megasessions)
Rahal (all around great doc)
Alexander (most natural hairlines I've seen, not sure on how many grafts he can get)
Shapiro (all around good doc)
