Not being a lefty I can’t comment from personal experience on potential drawbacks there. Maybe just that a wet writing stub might not be a lefty’s best match. I’m guessing you’re gonna want a pen that writes fine and dries near instantly. Or else you’ll smear your writing all over the page.
I still have to say it’s my favorite pen overall. It beats out very tough mid-range competition like my Lamy 2000 fine, Waterman Carene stub, 4 different Platinum 3776’s, a couple of Pilots and Pelican 200’s, all my TWSBI’s, a drawer full of really excellent Chinese (Pen BBS) pens, etc., etc., etc. And let me avow that I am REALLY fond of all the ones I mentioned.
The Goulet stub nib helps it write well and finding the ink with proper flow to match it helps to. I can pick the pen up after a week of it sitting and it writes immediately...like the Platinum 3776. And I have no fear whatsoever that it will leak, etc. Plus I LOVE the orange color and big clunky size.
The fact that it was a gift from a brother here makes it all the more precious...unbeatable. Ya just gotta like a big pen.
