i use to write with my waterman with black cross ink as i like the pale blue hue of it. now i got a new lamy and i use the cross ink but i find the ink flow too much. i read and it said lamy ink is more viscous than cross ink. would it help with the ink flow of my lamy? or which black ink would suit lamy best, in terms of ink flow?

I found Lamy to be ok but I really like Waterman
Florida Blue ink in cartridges. Its rich in color.
Flow is very nice as well. It also dryed very quickly,
which I like. This also depends on the grade of paper
you are writing on.
I have to get some Noodler's ink, I only hear rave reviews
on this product.
I'm also working on making my own ink. Its a work in
progress.
Regards,
Pete

the tip of the converter is like a screw, but it was too thick to be fully inserted by the nipple.
at last i managed to trim off the turns. now it works perfectly
