I'm thinking of delving into the world of Japanese extra fines. Originally I was thinking of getting a Platinum 3776 Century extra fine. I currently have a soft fine 3776, which I love, and I also have fine and medium Pilot Vanishing Points (a Decimo and a Twilight VP), which I also love. I realized that I want something thinner for a pocket pen with waterproof ink. (Right now I have a Dollar Pen with Carbon Black, and that definitely does not work well on normal paper.) Does anyone have both the Pilot and the Platinum, and would the Pilot be way smoother than the 3776?
Also right now the 3776 is half the cost, since I could get one on Amazon (with prime shipping!) for $70, but a Decimo from JetPens would be $139, and the ones on Ebay/Amazon aren't that much cheaper and would take forever to ship to the US. I think if I were employed right now I wouldn't hesitate on the extra fine Decimo, but I lost my job in March. Then again, maybe I'll hate the Platinum, since I wonder if I only like the soft fine because it's soft and fine. Maybe I should just put a waterproof ink in the fine decimo or soft fine platinum I currently have, and not buy a new pen at all.
