Feed Adjustments For More Flow On #2 Waterman Flex Nib Pens?

[Addertooth]

I have a pair of pens, one a 452 1/2V and a 552 1/2V pens with nice flex nibs. Both are very flexy and require very little pressure to spread the tines.

One pen is luciously wet (serious waiting for the paper to dry before touching), and I am happy with it. It will gladly flex and leave a 2mm line repeatedly with no railroading.

It can draw a 2mm line the full length of a page without ever missing a beat.

The other pen (which is equally flexy) has trouble getting enough ink and will "railroad" at anything over 1.5mm. How do I adjust the nib/feed/section relationship to get better flow and less railroading

on the pen that only does 1.5mm before it railroads?

Some here might say that 1.5 mm is pushing the nib past its limits, but maybe it wants a slightly wetter ink. I like my inks on the dry side, as I’m left-handed and smearing is an issue, but you might have a look ‘round the ink forum.

Okay, I will try the same ink the 2mm pen is using, Diamine Wild Strawberry. Or alternately, I will try Faber Castell Carbon Black, which is used in my other 2mm pen. The nib in the 1.5mm pen is the most noodley of all of my nibs, it just railroads at 1.5mm. It is very paintbrush like, but writes dryer. I have had amazing luck with 1920s number 2 New York nibs in some of my X52 1/2V pens. I really need to try a true wet noodle, so I have an actual point to compare against.
