I would be careful equating neck length with total mass in sauropods. Small 
Euhelopus had a quite long neck, medium sized Omeisaurus a very long neck, and 
the very long necked mamenchisaurs very very long necks. We do not know 
entirely know the neck length in the very biggest sauropods, but it was 
probably not 
exceptional. The super duper sauroppds were already so tall at the shoulders 
that very long necks would have violated the 15 m maximum height due to 
hydrostatic pressure issues.
