Want to buy Syaraku 2 1K, is the piston worth it compared with the ordinary version?

A big problem of Syaraku 2 1K (large) is that the capacity of inking device is too small. I have to use a grid of 2 1K M, 1.5 to ink the paper, which takes about three pages to write. The piston has a large capacity, but it is said that the piston is not as durable as ordinary ones. This is uncertain.

2 1K M has a strong sense of writing, and its outstanding feature is softness. It cracked with a little force, but it wasn't that kind of unrestrained cracking. After a certain strength, the splitting range has not changed much.

I'm only talking about the sense of writing with a big m-tip. It is said that F and e F tips are polished differently. In addition, the standard version is harder than the large-size writing, and the standard version actually has a small pen holder, so unless the hand is small, the feeling of holding the pen is not good.

Advantages:

Soft, expressive, comfortable grip, reasonable weight, very suitable for practicing calligraphy. Work depends on who you compare with, and it is worthy of this price.

Disadvantages:

How soft and less elastic. Because it is soft, it is not easy to control the pen, the writing speed can't go up, and it will be tired after writing for a long time, which is not suitable for a lot of daily writing. In addition, the initial writing is slightly scratched, unlike writing with a dragon pen, which has a uniform and delicate damping feeling like the oil on the nib. The inking device has a small capacity.

Another kind of iridium particles is not very wear-resistant. In fact, there is not much exaggeration, but the wear resistance is relatively poor. The Japanese call the pen a perpetual pen, which is durable.

Is it appropriate to enter the piston? Big 2 1K basically focuses on calligraphy practice. I have this 1.5CM grid in my hand, and I have to re-ink it after writing about three articles, which is estimated to be less than 400 words. Anyway, practicing calligraphy at home is just a rest, I can accept it.
