For cluster analysis, more is better. Haplotypes of 80+ STRs make it
pretty easy to spot trends. Our "amateur" databases of extended
haplotypes are now making possible what would have been entirely
impossible for academic studies to fund just a few years ago. Even
now, most academic population studies depend on minimal haplotypes. Pat
