I think you got the key to it... but backwards.
Just set the bandwidth on the loopback to 1.
As EIGRP uses the minimum bandwith along the path, this will effectively
take the bandwidth away from the equation, because the minimum bandwidth
will be 1 for all path. Then all that is left is delay... and that was
the problem goal.

set the bandwidth as high as you can on the connected interface for this netwo
rk (like 10 gig), and since EIGRP uses minimum bandwidth for calculations, that
will get you as close as you can otherwise get for the bandwidth component, na
mely 1.
