A thinner metric ring pack would allow for a longer rod without the piston pin getting into the ring lands. I will leave that rabbit hole alone for now.

I agree I don't want to build anything with bigger than 1mm, 1mm, 2mm. The OEM's are nearly that thin and they will sign you up for a 120,000 mile warranty.
