Back to the original topic... I'm most likely going to get the 911 because it's extremely cheap where I am ($1.88) and also one of the other pens in the OP.
I've narrowed it down to choosing between the 163 and 165 and I have some questions for those who may have either of these pens:
1) Do they have the same nib?
2) Are the nibs #5 or interchangeable with other #5 nibs?
3) Has anyone tried exchanging the nib on either of these pens with a flex nib from a Noodler's Nib Creaper?
I have a Nib Creaper that I can't stand but the nib is okay, so I'd like to put it in one of these pens.
Thanks in advance for any thoughts and advice!
