Fude Fountain Pen with Piston ?

Hello.

I do drawings like this one (1) I have two fude nib fountain pens: Hongdian pen with converter and bent nib 0.5-1.2mm (2 left) Inkursive Manga pen (2 right)

I love my Hongdian pen, but the ink capacity is limited compared to the inkursive. (3) The inkursive has a greater ink capacity but its nib is shorter and less useful to me. (4)

I'm looking for a fountain pen that would combine the ink capacity of the Inkursive and the amazing bent nib of the Hongdian.

Can you point me in the right direction?
