The pilot customs represent absolute best value
If you want functionality first, this is it. this isn't a pen for show; it's a pen for writing. picked this up because it's a demonstrator, and a piston filler, and a pilot. got some interesting, unusual iron gall ink. one has to be a bit careful with this ink...like, don't leave a small amount to dry out, and rinse it more carefully than normal. thus, the advantage of a demonstrator. plus, my intent is to use the ink in pens dedicated to it. just to avoid any poor interactions. it's worked great with those inks. excellent flow. the nib's mildly responsive when i want it to be, but easy to handle too. body size is right where i like; some might prefer something chunkier.
