Kinetic! I think your images would have been even better for me if they were sharper (less Blurred).
I think the 0.40 is too big and 0.30mm might be a safer bet to get more details.
I am no expert but from browsing the web my gathering is that this hole should be smaller and there is an optimal which I am also hunting for.
I have been on 4 different sizes myself but still not happy.
