I have the roller ball equivalent of this pen and it's amazingly comfortable to write with...EXCEPT...with the roller ball, the pen naturally rotates 45° and my thumb naturally rests on the flat face. Unless you can rotate the nib to accommodate that grip, I see this fountain pens ergonomics as problematic. If the discussion moderator can verify nib adjustment, I'll buy this pen. Also, it's not a large pen. It works for me because I don't have large hands.
