It's been awhile since I've played the Gold, but the plating doesn't seem to be any particular advantage. It's different, but both can go dry. My experience is that the Black, when wet, doesn't build up like metal can. It doesn't "scum up."
You'll eventually get a balance between too dry and too wet. Too wet is preferable; practice should take care of accuracy, while too dry can really mess you up.
If you're playing dry, try drinking some water before you play, to be hydrated.
