I spent days reading reviews, watching videos, etc before getting one... so here's my small contribution (nothing new but then I didn't mind a single time reading again and again the same reviews so...)
I flushed the pen, brushed the feed (the usual water, 10% ammonia, a drop of detergent) just to be on the safe side.
Very smooth, even when flexing hard. Very wet too: it made Diamine Syrah look really dark when other pens show it on the pinkish side, it made Parker Quink a real black.
Easier and easier. The variation goes from hair thin (because of the speed, otherwise it's a M on the fine side) to 2 mm. I flexed like mad for hours on end without ever railroading. I've had this pen for two weeks and gone through many many refills without a single problem, doing entire pages of nonsensical flex. Now I'm experiencing some railroading then nothing for hours, but before I tinker with it I want to understand what is going on. (I haven't noticed that the breather tube changes anything and prefer to leave it on as I would probably lose it otherwise). Even with the current hiccups, I am as pleased as I can be.
I don't want to get it into the "oh you can't call it a flex nib" but here's what I mean: I've only ever had normal pens with steel nibs, none of them can do what the Ahab does. I've played (and still play) with dip pen nibs and none of them would ever become an everyday writer. And I get to do things that can pass for pseudo-calligraphy. I have the best of both worlds...
I expected the Ahab to look kitsch, or cheap, or completely ugly. I had chosen Iroquois and am really pleased with the material: subtle swirls that go from copper to grey to dark brown streaks ... really beautiful.
I would buy it again, had no idea I would love it so much. As a side note, I bought it for the good and the bad reviews: the good ones made me dream of it, the bad ones made me want to make it work for me. I've had it for two weeks, used it every day for long sessions of inept flexing and normal writing, and many many refills. I really hope this pen lives forever.
