My recollection is a bastard mill file leaves a rougher surface but will have to give it a try if there is a mill bastard in my file assortment.

Here is an old thread > https://sawmillcreek.org/showthread.php?255103 < scroll down to see a post with some comparisons of different rasps and files and the surface they left on some pine.

The smoothest surfaces where left by sheer files. (the Superior Standard is one of my favorites to use for smoothing.) They are more like a float than a regular file.
