The smoother the surface you start with, the smaller the surface texture that the seasoning needs to smooth out, the harder it is for food to grip the surface.
I am tempted to 1200 grit random orbit a pan and see how good life can be.
Just get a carbon steel pan instead and save yourself some trouble.
Once seasoned it is much more non stick than cast iron and It also is lighter so easier to handle.
I didn't go that crazy, but I did use an orbital sander on a cheap Lodge cast iron pan, and it's much more non-stick now.

Why not both? Besides, you can't make home made baked beans or a good stew or bake bread, cakes or pies in a plain high carbon steel pot.
If you push me to it. I will be happy with just my plain high carbon steel wok and cast iron dutch oven.
I think the max I used was 600, possibly 800, and it made a huge difference. If you use 1200 then that'll be one sexy pan!
Go like a real man 2000 grit..
