I am planning to purchase a Lamy Safari as an affordable first fountain pen, but I am uncertain if I should go with the fine or medium nib size. I know that nib size is going to be a personal preference, so to help you guys help me, know that I really dislike using 0.5mm "lead" in my mechanical pencils and much prefer the perfectly sized 0.7mm "lead". Would the fine or medium nib size be closer to my beloved 0.7mm sized mechanical pencil "lead"?
Also, are nib size universal across nib manufacturers?
