TWSBI Diamond 580 vs Jinhao X750

a Diplomat Aero. This one is *hefty*; it was one of my first heavier pens and I love the way it feels in hand.

Weight wise it’s comparable with her current Jinhao x750. It’s a great fountain pen and I would recommend the medium on this one only because Japanese nibs are ground finer for finer lines than most other nibs.

The price for such a good fountain pen is unreal. Pens of similar writing quality made in Germany, Italy, or Japan cost 2 and 3 times as much.

I find vac fillers interesting and fun and am really glad there are affordable versions on the market. For under $10, I think the Jinhao X750 is fantastic. It feels and looks classy, it’s smooth as butter, and I genuinely think it might be the best value for money of any fountain pen I’ve tried.

5 ultraflex in TWSBI 580 and it just didn't work - the inkflow wasn't there. Every #6 nib I placed into PenBBS struggled to function (and taking out the feed each time was a literal pain I do not want to repeat again). I bought Lamy nibs by mistake and don't even want to start down the Lamy road, so I'm leaving those untouched. I still love all the pens I have, but for future purchases, I think I'll stick strictly to the pens that take #5 or #6 Jowo nibs without much of a struggle in the feed

I have rejected Dryden and AmazonBasics pens for being too difficult to hold, especially for longer writing sessions, because they are both too slim and too slippery. I just got the Jinhao x750 this week, and I think I might like the grip, but something about it encourages me to use more tension in my grip. I need a pen that I can hold without too much tension in my hand/wrist.
