induced drag is fairly low and certainly lower than the weight penalty of a heavier tail.

Are you suggesting that a tail with a higher aspect ratio would be, by
definition, heavier or talking about the tactic of putting additional
weight in the tail to move the CG?

Good stuff.

Heavier construction. Heavier stabilizer means larger moment of
inertia, higher torsional stiffness of the tail... leading to maybe 4
or 6 times as much "extra" construction weight as only the extra
stabilizer weight. And you have to correct that with even more wing
surface ;-)
