This will most likely (effectively) be answered by David vdS,

I have been interested in using a polarizable water model via gmx, and have
been looking at similar models to the shell model in gmx.  I was looking at
the Drude model of Roux
and co-workers in J. Chem. Phys. (2003) 119(10) p. 5185.  I noticed their
dielectric constant appears to have converged very quickly compared to the
rigid shell model in the publication.  Is there any rationale to explain
why? Have there been any improvements/changes on the shell model? In the
publication, it is mentioned that the model may not be sticky enough ... is
there any way to improve it, or is the model tweaked as far as it can go?
