I'd like to try this, but it is quite expensive compared to Zebra Sarasa or Pentel Energel. The metal body is interesting, I wonder how different is the weight and feel to pens with plastic body.

The difference in feel is significant.

What is best is a personal preference. Some people like their pens to be as light as possible. Personally I far prefer the solid weight of my Rotring 600s. So I recommend that you try it out.

I use one and it feels very heavy, almost unnaturally heavy, and indestructibly solid.

Not at all uncomfortable once you get used to it, but the first time I pick it up after a few days my reaction is still always “wow that’s heavy”.

I love the Zebra F-701. I'm also going to try the pen in this review, but wanted to give a recommendation to the F-701, as someone who hates to write, I like that pen.
