If you haven't been keeping up, Go 1.21 reduced overhead from ~10% to ~1%. 1.22 overhauled the format to improve reliability and add information. 1.25 has a built in trace flight recorder. And we have an active proposal (go.dev/issue/62627) for a trace parsing package to enable arbitrary tooling.

G2's are great. I carry a G2 0.38 with me at all times (when a fountain pen wont be practical). My everyday handwriting is tiny and requires a finer point. I was very unhappy with my Lamy 2000 until I sent it to a nibmeister who ground it down to a Japanese needlepoint. Now it's among my favorites.

Just adding my two cents here. I really enjoy Platinum carbon black and Sailor kiwaguro. Get some samples and see what works for you.

That makes sense. I've gotten into fountain pens lately (and increased my attention to mechanical pencils). Writing things down in general has been helping me declutter my mind and workspace.

Have you tried any fountain pens? Like a Lamy 2000?

Out of curiosity, what do you prefer to write with (pens, pencils, etc.)?

That is the next logical step.
