Workhorse pen(s) recommendation
This is not going to be a request for recommendation. Instead I'd like to share my opinion and experience with pens that I tested at work for some time.
I take a lot of notes at work, especially when I have to deeply understand some problem but the important part of my note taking is that I dont usually write a lot for a long time. Instead I keep opening and closing the pen all the time and write down only little bits.
It has always bothered me that I had to unscrew the pen each time and was worried about the threads possibly wearing out.
That's why I ordered the Pilot Capless first. This was the first big upgrade to my note taking - it's super convenient to be able to "switch the pen on and off" without screwing and unscrewing the cap. Plus the nib is exactly the way I like it - no feedback, super smooth and just a little bouncy.
After some time, because someone has shared their new pen (and because I'm weak), I fell for it and ordered a Diplomat Cobra for myself too. This was the upgrade number two. I really love the magnetic cap - I can open and close the pen super quickly and conveniently without worrying about the wear. The nib is something that I had to get used to in this pen. It's very rigid and much more juicy than I typically prefer. I'm still trying to find an ink that will work best with this pen but the Sailor Studio that I'm currently testing looks very promising.
I hope it helps someone especially if you're overthinking stuff like me.
