Quote - Vicky 6 vs Mike 6. Both are the exact same mesh, so they have identical topology.

Actually the topology is slightly different between the models. They have the same poly counts, but the distribution of the polys are more concentrated in some places than others. For example the female has more polys and a different flow around the breast area than the male. I believe the hips and limbs may be different as well to account for more male muscularity.
