Do a few test runs and see. I would think the cutoff value would more
strongly affect the lipids, not the ligand, whose interactions are
comparatively few and relatively local. If you use the Verlet cutoff scheme
in version 4.6, it's largely irrelevant since there will not be any
"missed" interactions either way.
