That's a tough one!

I've taken them and put green circles over things that caught my eye,
which i would probably have done differently. There are surely many more,
but i just wanted to show you what i looked for.

elsie2 is missing a lot of traces (ground), so that makes me think it
might have been the autorouted one. But then those signals would have been
too easy to route, why should the router not have made them?

Elsie1 has a lot of "ugly corners" but no vias at all. elsie2 is neater in
most corners, but has several really unnecessary vias.

No, i would hazard a guess you routed elsie1 manually and you simply care
much less about how it looks than i do.
I would prefer elsie1, with a few pushes and shoves i could use it as a
finished layout, but basically, neither is what i consider finished.


By the way what is this? a LC meter? i just bought a automatic RLC meter
off ebay, maybe i should have asked you first? ;-)

thanks, and do tell which is really auto.
