I don't know what could be so different about a new cast iron anything. OK, skillets might be pre-seasoned...

Don't be too quick to delete the grille. You'll find the downside of a flat top gridle is the aftermath, cleanup and maintenance. A tin can of drippings to dispose of, stones to scrub it with, spray/coating to prevent rust. I've got a grille, a gridle, and a deep fryer. I'll put Yoshi Grille mat(s) on the grille rather than feck with the gridle when I can. Cheers
