We need to play the six off of the midpoint.  That point is badly overstacked, and unstacking it now is a priority.  The other two ways to play the six either expose the runner to a triple shot or uselessly slot the deuce point.

Then it's a question of where to play the one. Slotting and splitting is usually ill advised (see Magriel, chapter 17) so 24/23 is likely incorrect.   7/6 seems too passive, 6/5 seems too risky, and 3/2 accomplishes nothing.  That leaves 8/7 as the only remaining option.

13/7 8/7

No board to worry about, so I too say split at the back and bring one down, unstacking the mid, with 24-23, 13-7.

The Herd chooses correctly again.  I guess Magriel's admonishion against slotting and splitting doesn't apply here.
