You can find part 1 here. You can see that there is a slight bit of show through with the Stillman and Birn Epsilon, but at only 150 gsm that’s to be expected.

I decided to play a bit more with ink colours and wider nibs here, so that’s a Sailor medium stub nib and Diamine Inkvent Blue Edition Candy Cane ink for spells and effects:

There’s no show through for the ink, and though it may not seem that way, there was no spreading. Also, if you like granulating watercolour effects, the Stillman and Birn Epsilon paper seems to be a champ for that.
