This is the second brown ink I am reviewing together with the Vaikhari - it is a nice medium brown from Noodler's - called Kiowa Pecan. I haven't had much good luck with Noodler's inks - for one reason or the other, most of them havent worked well for me. This one though, is probably the Noodler's that I like the most and gives me least trouble.
In comparison with Vaikhari and Iro Yama Guri. N-KP is lighter than both , though some shades are very similar to Vaikhari - However, the Vaikhari has auburn/ burnt sienna tinges on the lighter shades and Kiowa Pecan's lighter notes tend toward golden browns.
Dry times are on the longer side; about 30 secs on these scrubbies with a Bock F nib. But real life writing seems to dry much faster.
Overall: I really like the color and how the ink behaves with most papers. the shading is beautiful, encompassing a wide variety of browns. This is a great ink from Noodler's.
