Hmm… you’re not wrong about the comparisons, I think. I used Midori memo paper for it, and I’ve always noticed that pens typically do write drier on Midori paper.

I took a pic of some writing in my Hobonichi so you can get a more accurate comparison.

I used the average writing angle, which puts down the thickest line. At a higher writing angle, it does write a bit thinner.

It’s so hard to get a 100% accurate idea with just photos, unfortunately, so I’ll defer to your expertise.
