Gord,
Concerning the weight shift and CG movemnt to get better cruise economy.
SNIP:

FWIW the L1011 was operated that way - retaining fuel in the #2 outer
tanks moved the CG back in cruise flight to reduce horizontal tail
trim drag. This fuel was used later in flight, of course.

Thanks Walt, I hadn't heard of using 'wing fuel' that way but of
course it would work, might not be quite as effective as tail
tanks because of less moment being available at the wing tanks
