  We revisit the three black hole scenario with numerical relativity techniques
to study hierarchical configurations where the inner binary contains highly
spinning black holes. We find that the merger time of the binary gets a delay
(with a number of orbits to merger increase), depending strongly with the
distance to the orbiting third hole $D$ as $\sim1/D^{1.6\pm0.1}$. Notably, a
different dependence from what we had found in the nonspinning case,
$\sim1/D^{2.5}$. We interpret this effect as mostly due to a spin-orbit
coupling between the third hole and the closest member of the binary in the
successive approaches. This lead us next to study scattering configurations of
the third hole with the binary in order to evaluate the extent of this
``sudden'' interactions, finding also a correlation of the delay in merger
times with the closest distance, even for the nonspinning cases. We then
explore the mass ratio dependence of the triple system by modeling binaries
orbiting a larger black hole bearing masses ratios 8:1:1 and 18:1:1 in
co-orbiting or counter-orbiting configurations, finding merger times increasing
with increasing mass ratios and for the counter-orbiting cases.
