I found out the hard way that the Wality nibs used on the Airline pens cane be 'variable' in quality.
I blamed the pen and disposed of it. It was an ebonite Wality 69, my first Eyedropper and my first Indian pen.
I learned how to treat a scratchy nib with micro-mesh to make it write smoothly. It is a very fine abrasive pad.
I have a Wality 69A and a Click Bamboo that are both fitted with Ambitious nibs.
The Click needed corrective action & I can imagine how disappointed you would be if you had parted with hard-earned money on it. I treated it to an Ambitious nib because that is what I had in Medium tip for the India #8 size.
If you are using the pen at work, then the available paper may have been bought in to feed a photocopier & is too absorbent of fountain pen ink. Therefore if your writing is very small it won't look very nice at all. The paper fibres soak up the ink very fast & the writing appears to spread out. We call that 'feathering'.
There is not much that you can do about really bad paper in a workplace.
