An update on my cartridge-only Kaweco Dia2 with a 14K B stub:
Pendleton recently completed my "B" size (BLS) stub & adjusted the problematic Kaweco 060 feed, to give me a richer flow of ink. I'd guess this beautiful grind to be either 0.6 or 0.7mm, ideal for daily writing chores when a narrower line & a smaller script is required.
The biggest positive change with the Dia2 has been that finally I'm getting an adequate amount of ink delivered to a nib that has been adjusted on the wet side.
At last the pen is working as it should.
The key to this success has been the choice of ink (in cartridges).
Dry inks like Pelikan 4001 b/b or even Kaweco's own Midnight, did not perform as well as Waterman's. At present I am trying out all the Waterman flavours of blue & green carts. My project will be to try out the best behaved, free flowing inks that are available in international short carts.
A beautifully stubbed 14K BB (BLS) is now back at Pendleton's shop so that he can work on the feed's channels. I'm hoping to get this other nib back soon.
Here is my new B (Butter-Line-Stub):
