I'm not sure I follow your reasoning about the heavy
glider having the advantage in the 2G case.

In normal flight at high speed we have relatively little
induced drag, and the major component of our total
drag is profile.
With it's higher reserve of energy the heavy glider
gains the benefit 'cos even though the induced drag
is higher it's a small proportion of the total.

If we now start to pull G the induced drag for both
gliders goes up, it now becomes a more significant
proportion of the total for each glider so surely the
advantage of the heavy glider is reduced?

(And I notice that you have admitted you're in the
'Heavy Glider Wins' camp) :-)

sink rate in the 2G case for the same reason that it
has a
lower sink rate in the 1G case.
