I chose a medium nib for smoother writing, but the 1st impression was not good. At the beginning it was quite scratchy that ended up tearing the paper. I had to remove the nib, clean it again and fine-tune it. I managed to make it smoother, but the ink flow is not as expected. It certainly needs more work with the nib and still...I can't tell if I'll ever manage to make it a proper writing tool....the point is that for its price you should not spend so much time fine tuning the nib, in fact you should not deal with this at all.
