@mroldboy: I didn't want to delay getting into Phantom Pain by trying to unlock all the stuff in Ground Zeroes first so I downloaded a 100% save. It worked a treat for me. You can get it here if you're interested: http://www.savegamedownload.com/metal-gear-solid-5-ground-zeroes-save.html
Already had the save. I never even considered trying to 100% GZ. I only want to play it for the story and to get a feel for how MGSV plays.
