Both your Jinhao pens use the same cartridge and converter. (I like big, fat, heavy pens.)
You have a good range of selections. Which do you find most comfortable in hand ? Of the others, what would you change to affect improvements ?
Take time to enjoy your acquisitions. There is plenty of time to go broke.
I actually don't like either of the Jinhaos, because they are too heavy!
Weight wasn't something I was considering when I ordered these, but now I know to consider that.
I seem to prefer lighter pens. Of this beginning, I love the greens, am okay with orange, hate the reds.
Lamy Safari - Plastic
Lamy Vista - Plastic
Jinhao 159 - Metal
Jinhao X750 - Metal
Pilot Metropolitan - Metal
Kaweco Sport - Plastic
Noodler's Charlie - Plastic
Noodler's Nib Creaper in Midas Pearl - Plastic
These likes and dislikes tell me I prefer lighter pens.
The Jinhaos made my dislike list because I find them both awkward and heavy. At some point, I will give away or trade the Jinhaos. I've tried them both twice, and hated it both times. I really wanted to like the Shimmering Sands one, my inner teenage girl was screaming with joy at the sight of it, but no.
The Pilot Metropolitan was the first pen I got (followed immediately by the Lamy Safari in bus yellow) and I thought it was great, until I got the Lamy. It's just ranking OK with me now. I want to keep it though. It looks nice, and writes okay for me. I'd like to get a broader nib if that's possible, it's got a Medium which writes too thin for me. The Lamy Mediums are perfect.
The whole reason I ordered the Kaweco Sport in Mint was because it was plastic. I read my list of Wants and there it was waiting for me to buy it in its plastic goodness.
I hate it! Want to trade! The pen looks great, the nib is a nightmare! I almost got two Preppys, with plans to convert one to a dropper, but I got this Sport instead and I should've went with the Preppys.
Now the Noodlers. Both of them, I disliked when I got them. Both of them, I now love. I've seen videos of people heat setting their nibs, I haven't done that yet. But I love the pens. When I ordered the Heart of Darkness ink, I thought it'd come with a Preppy but I got the Charlie and once I saw the Noodler's video about it, I was so glad to own a Charlie. I filled it with boring old Heart of Darkness and can't wait to change colors. It really matters if you wash them out first. I didn't realize with Noodlers they need to be washed out before you use them.
