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.
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 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.
