I had my head & shoulders scanned in the past and my HRTFs produced by IDA have worked very well for me. Unless they have changed their approach, and as far as I know, they do not measure features or try to match anthropometric dimensions to HRTFs in a database (which is still problematic since matching of specific anthropometric features to the fine structure of the HRTF is still an open research question), instead they do a full computational acoustic simulation of the HRTFs that takes into account the whole scan as it is.
