Hi all,
I am trying to decide between Visconti Opera Master and Waterman Exception Day & Night as my next "heavy" elegant pen. Both apparently weigh at 1 3/4 ounces, but the Opera Master comes with a piston filler. Good thing about the exception are that it has a better, smoother nib out-of-the-box (correct me if I am wrong here), and is much cheaper. But, sadly, it has a cartridge converter that I don't really like. I hate to fill it up more than once a day and I write a lot.
So, any idea if this pen is suitable for ED conversion? Any internal parts uncoated metal? If so, which ones? Any other openings in the barrel (breather holes) other than the main opening for the section?
Thanks!
Stanley.
