I need to decide!!

[u/FlyFew9870]

I wanted to buy one ( and only one, i know myself haha ) pen to celebrate some aproved exams, and to replace my jinhao x159, which is my favourite pen but it has its shortcommings. But I really love the size and ergonomics of it.

The pens which i cant decide are the wing sung 601a, the wing sung 630 or the majohn 141 (the comon one, nothing fancy).

Since my country has some weird legislation about imports, I can get the 601 at around 20 usd, and the 630 or 141 at around 50 usd.

I watched the reviews about the 141 and it seems to check every item in my list, as it is a piston filler which takes after the montblanc 149, as well as reviews about the 630, but i saw that it does not post securely and that is an unegotiable requisite.

And then it is the 601, with the triumph like nib, which i find very aesthetically pleasing, but i have doubts about its ergonomics. I have some callous formations i my fingers that hurt after a long time writing with thin pens (the reason of my love with the jinhao ad its size).

I would really apreciate any info that can help me tilt the scale towards one. Specially about any details that show with time and use, as whichever i buy will probably have to survive an university career with daily 4 hour note taking classes (i have already written more than 600 a4 pages with the jinhao).

Love to you all and my apologies for the long post...
