Newer Iron, produced after the introduction of the Desi machines, is all going to be much rougher and more textured. Not just the Lodge pieces.
I have had less sticking on the "newer" Lodge pieces (1960 forward) than with some of my very finely ground older pans... that require some/more time to build the seasoning or more coats applied at the outset.
As users, they can be real workhorses.
I just started using my Wagner Angus Broiler recently, which has a quite 'rougher' interior texture, with grids. I restored it over 2 years ago, and set it aside (hairline crack at a spout). Stylized logo, w/made in USA is the indicator of 'newer'. I thought is might be a mess to clean up,with the rough surface.... as the drippings really can burn on... not so. Short soak with hot water, small plastic bristle brush for the 'grids', and it's good to go.
Lots of folks may not realize, that Griswold, Wagner and other makers began preseasoning their pieces back in the day also. 1940's, possibly earlier... Was this done as a convenience? or to offset changes in the methods to produce the piece?
