I'd tighten IN a touch and widen ST just a smidgen.

I second Birdseeding. Looking good as a whole.

You asked whether something obvious sticks out? No it doesn't it looks rather fine as it is. I'd only loose /PING/ a bit to match /STROM/ better.

Thank you, gents. Will try and tweak as suggested.

Agree with all of the above :-)
