Grease or Disks for 5th Wheel Hitch Plates?

[ccmret]

What is the preferred method to grease your plate on the hitches? Do you prefer the grease disks or traditional grease? I am using a B&W Companion Hitch

I am using a disk, but I have only camped once 😉

...yes, totally not helpful

I don't know of any 'grease' disks, but the plastic ones work fine by themselves.
