Hi everyone, I'm looking to get a CH912 as my new everyday use pen, but I'm taken aback by the sheer number of nib choices. I have a two main questions: - What is the FA nib like as a daily writer? Is it relatively smooth? I have heard of flow issues regarding this nib. I am not a tremendously fast writer, but regular skipping would be rather annoying. - How does the Wavily nib compare to the SM, or just the regular medium nib? Is it any smoother? Any help would be greatly appreciated.
