Many people like the FA nib. Some have modified the feed to get a little more flow to keep up with their writing style. I just want to make sure anyone reading this does not think I am saying the nib is bad.
But I think you will see what I mean when you read over the reviews. There likely is something on Youtube for each of these items.
I think a lot depends on how you write: speed, size, paper, print vs cursive, degree of pressure you use etc......
I suspect you will really like the soft fine even if it turns out not to be exactly what you want. And the resale value is there, so until you are sure you do not want to sell it hang on to the paperwork, box, etc..... as that always seems to increase the sale potential.
Report back on the soft fine. I want to try one some day, but right now my wallet is a bit dry.
Strangely, this one I ordered has a nib which appears as silver - but is actually described as gold 14K, so I assume it is plated with something.
I have tried SF before (nib with standard gold appearance), but swapped it in for a SM because I found the SF's lines were too thin on average (it is said that Japanese grades are finer than Western nib grading, so that a staggered correspondence obtains, i.e. Japanese F is actually closer to Western EF, Japanese M closer to Western F, etc. - of the truth I don't know but that stuck from reviews I have read).
Ironically, the replacement SM turned out to be produce lines that were thick for my small writing - specifically, line variation was lost as pressing too hard resulted in lines too thick for my small writing, so I would avoid pressing hard and therefore flexing altogether. So now I'm back to SF. I speculate that something between SF and SM would be suitable for me, but this only exists in my imagination.
The most notable feature of the Falcon pen nibs (not the FA nib which I haven't tried yet), is a rounded tip. I dislike this, because it tends to make writing appear regularised and consistent like a ballpoint, thus undermining line variation. However, the Falcon (along with Nooder's flex lines) remains the only modern pen that gives line variation at all, and hunting for Vintage pens is too much hard work. I like a mint pen; I do not like the history and wear associated with user grade Vintage pens; and mint Vintage ones are overpriced. I prefer a pen that is my own from the beginning, and the assurance that comes with a new pen, with modern standards of warranty and QC.
Now I am itching to try an FA - my wallet is about to take another assault. I've been spending far too much on pens lately on the personal quest to optimise my writing. In particular, I have been experimenting a lot with line variation.
I hate how people don't post writing samples, and I'm about to become guilty myself of this neglectful practice, as my computer is too cluttered with activity; I will consider posting a sample later. Or better yet, perhaps start my own blog documenting my journey with fountain pens if I have the time.
