Most of my pens write slightly wet - it really helps with smoothness. I have increased the flow successfully of several Chinese pens (Hero 704, and Picasso) and they now write really well without being overwet or causing a mess.
One of my best is a Swan Mabie Todd which is near a 10.
Sometimes, when it is less than half full, if I take it out in a hot room from cold, I have to shake the ink back into the sac to make sure it does not drip out a blob on the page when the nib touches the paper.
Once it has settled to the environment temperatures all is sweet though and insanely smooth
I would not take this pen on an aeroplane! (unlike my Waterman Kultur/Phileas with convertor which behaved admirably!).
