This is a great nib unit and an amazing value.
This is not the most flexible flex nib I have but I like the thin EEF line that it begins with and I really like the controlled manner with which I can achieve flex lines. I want to really emphasize the degree of control that is possible with this.
This is a great drawing nib and I value control over maximum flex.
This nib finds a nice balance between smoothness and feedback for such a fine nib.
I used an Opus 88 Demonstrator with Noodler's Lexington Gray.
