I did own a Conid kingsize monarch, exclusive to fontoplumo with a titanium F nib. It was one of the smoothest F nib I had ever used. But I didn't like that pencil like feedback of the nib material and the tendency of orange ebonite to absorb ink, so I let it go. My fascination with filling systems won't last more than 6 months, so unless they make a pen with some stunning material, I'll stay away.
