There is a strong focus at ts.com on concert taping. In open taping situations, people often like to have their stands at 8-10' high. It's nice then to have a stand that is 9-12' high so you aren't using the stand at it's highest level (most extended, least stable).
Thus the focus on light stands. There aren't really any mic stands in that size realm, only light stands. Plus positioning mics for concert taping doesn't have the same requirements as positioning an on-stage vocal mic for a guitarist to use.
