Well... I ended up getting the customized and tuned version of the Jinhao 911 called the "Thyer" thanks to a tip on another thread here. It's a lovely pen with a very smooth nib writing a nice F (the seller says 0.45mm and that looks about right to my eye). Next chance I get I'll write a little review of it.
As for the other pens in the OP, I've got the 165 coming in the mail (I went for the matte black finish) and also one of these new ones I just came across, the Jinhao 992
I can't wait to hear your thoughts on the Thyer, this is the first I've heard of it, though I now found it mentioned in the Chinese Pen of the Day thread.
I also have a 992 in the mail, both a clear and a blue one. The interesting thing is that it is not in their 2017 Catalog.
