[gmx-users] forcefields for lipids

Dear gmx users,
Imagine it's a protein-membrane system which GROMOS53a6 and CHARMM36 will give me the same acceptable output for it. Now if I want to choose one, what am I supposed to chose? How can I have a good option? Any suggestion? Or any articles available?
I guess the CHARMM FF is good because it would give me results in details, but is time consuming!
Thanks for your suggestions in advance.

Subject: Re: [gmx-users] forcefields for lipids
In addition to the ones already mentioned (CHARMM, GAFF/AMBER, Berger, OPLS-AA) there are several united-atom GROMOS based lipid forcefields (43A1-S3, 53A6L/54A7, 53A6 Kukol, etc.). The Lipidbook website is a useful place to find lots of lipid parameters in one location:
The choice of force field will depend upon what you wish to simulate. With PC lipids there are more force fields available compared to other phospholipids, so your choice of lipid may dictate your choice of force field. Additionally some of the available lipid force fields may work well for one type of lipid but not another. Finally if you have a membrane-protein system you also need to consider the combination with an appropriate protein force field.
