After working with this pen for a while, I have found that it is quite ink-dependent on the performance. I have found an ink which works very well and now the feedback has diminished and the ink flow is fine.
The inks I tried the first time I used the pen do seem to be on the dry side in other pens too, so I was perhaps a bit premature in only rating the Estie as a 4 star pen.
Much better now with an ink it likes and a few hundred words later....
Lovely pen in terms of visual appearance and feel in the hand. I am into stub nibs or at the very least broad nibs. The quality is superb and the finish is excellent. What I do not like about it is the writing quality. I have a $32 TWSBI Eco with a 1.1mm stub nib that is light-years ahead of the Esterbrook in terms of smoothness and ink flow. I have tried a few different inks in the pen but still it does not match the TWSBI in terms of writing ability.
To be as unbiased as possible, I also bought a TWSBI Eco in yellow and filled it with Diamine Amber ink. It too is a dry writer and is not at all compatible with the other TWSBI's that I have. So I suppose it is the luck of the draw if you get a dry one or a gusher. I like it and can live with it as it but wished it was a tad smoother and wrote like the $32 TWSBI.
Stubs do tend to be a bit on the dry side because of the ink demand, but for $200 why do I have to make apologies for it when for $32 I do not ever need to apologize for the TWSBI in any respect?
