That is up to you and should be chosen based on certain criteria you
or the field sets. E.g. do you want all atoms or united atoms? What
has been used previously on that system? In any case, the force field
used for the lipids should match the one used for the protein. If
you've parameterized the thing for a gromos force field, use that
gromos force field. And please don't let it be ffgmx... In case it is,
check the archives for reasons not to use that force field (or note
the word 'deprecated' pdb2gmx gives you).

On another note, don't include a whole days digest in your mail when
you reply! Please only include relevant parts. (Mark will probably
note that a while ago I gave the same remark, while automatically
including the digest again..., which I herewith want to set right ;)).
