Which permsissions plug in to use or none at all?

[chippewaguy13]

I've been fighting with my permissions and at one time even locked my players inside their home unable to break block or use doors, received a royal flaming.

Making very slow headway with permissionex, groupmanager, and bpermissions. Do I even need to mess with a permissions plugin now since there is a permissions file in the root of my server? Can't I just write my permisssions into that? I think world guard added it.

Also Am I going to have to go back and edit the permission if I promote someone to OP? or is one of the plugins going to handle this for me and I over looked it? This is on a server running bukkitforge any thoughts?
