I really dig the JoWo #6s I stick in Jinhaos, but try as I might I can't quite get them wet enough.
Just wondering what you guys think about the relative wetness of Bock and JoWo - and to be honest I'm more interested in how the feed performs.
if you are going to install a generic Bock on a Jinhao, you are likely to get the same performance as the JoWo on a Jinhao.
Ink flow is determined by nib slit gap and also the design of the feeder.
In general, IME the inkflow of the stock generic no 6 units (housing+nib+feeder) from JoWo and no 6 from Bock are roughly the same. I personally prefer the Bock slightly. The No 6 from Schmidt is quite a bit wetter in terms of inkflow, I understand they make their own feeds and housings.
