I try not to polish my blocks. Doesn't mean that I haven't done it from time to time to attempt to achieve a mirror finish just for the hell of it.
Often I find myself re-lapping my polished mirror finishes again to take away the shine, as crazy as that sounds, it's true.
I haven't found any evidence that a mirror finish is any better than a non-mirror finish, so long as the block is flat. Of course, flatness is something that is extremely hard for someone like myself to measure. I've carefully lapped blocks with 240-grit paper and achieved similar performance to a 1200-grit lapped block.
Mirror finishes are "wank value" IMO. Flatness is where it's at. Doesn't mean that I won't try to provide a mirror finish if possible. I often find myself in conflict with what I believe to be adequate (within reason of my meagre ability to make a piece of metal "flat" around the CPU die area), and what people percieve as good with wanky mirror finishes.
Hey, if it's shiny, it
has to be good! It's in our basic human nature, or why are diamonds so treasured? I'm no marketer. I'm just prone to the same desire for shiny objects like anyone else, despite what reason tells me.
