Did the Himalaya turn out to be a perfect match for Kung Te-Chung? My concern is that the cap won't seal tight enough to keep the nib from drying out if left untouched for a couple days.
That's a good question. KTC works well with the Himalaya. I agree with Jamerelbe in saying it provides a pretty adequate seal. The increased wetness of the Himalaya further decreases the likelihood of drying out
I do agree with you in your concern as it doesn't have an inner cap like the TWSBI or the Jinhao 992, but I feel it does a good job, but I don't think it's going to do as good a job as those pens with inner caps.
My experience with the Himalaya concludes to the point of saying: it is a good pen, but the nibs can be frustrating. I had a good Medium nib initially, and I placed that on my Charlie pen with KTC and it works fantastically and is still inked. I ordered another 6 Mediums for experimentation: OOTB 2 had a scratchiness that even with micromeshing remained difficult, and after micromeshing lost a bit of feedback I prefer. 1 was squeaky to a degree I dislike, but did work very well, 1 had too much feedback for me and would require micromeshing, and 1 worked well with no problems.
I feel as the Pen Habit stated in one of his reviews of FPR pens, they are tinkering pens. If you're OK with that and are comfortable with tinkering then I think they are great for you. The nibs are hit or miss OOTB. For me, I'm not a big fan of that.
I did experiment with replacing the nibs with TWSBI Eco nibs, which proved to fit well, but were even wetter. The TWSBI nibs I tried (F, M, Broad) felt great but went through too much ink too fast.
So for me, I hit a ceiling with this pen.
I think if you have a TWSBI Extra Fine nib you like then this pen is gold to swap it in with as it won't use up too much ink. If you get a good nib from them, it's a solid pen. If you're comfortable or good with tweaking nibs to your liking this is a fantastic value.
The FPR Himalaya has been invaluable to my introduction to ebonite and indian pens, but right now I'm looking for something with a little more consistency and reliability closer to my TWSBI's, my Jinhao's (mostly with Jowo's), my Franklin Christoph Marietta, all of these basically being Jowo setups.
This is my experience. As with pens like this I don't think this is how it always is.
This has a potential to be a good KTC pen. What is nice is that, like my Charlie pen, it puts down a beautiful dark line of KTC that my Safari Medium can't match putting down only a lighter hue, which I don't like as much. The ebonite feed makes the difference between them.
I hope this helps. I'm sorry for the lengthiness. Let me know that you think, because I'm in the same boat you are. I do like my Charlie-FPR M nib-KTC combo, but I'm always looking for something better and a little more consistent and reliable. I think I may go the way of experimenting with what ASA has to offer, since I love ebonite pens and they offer german made nibs.
