Though the Zebra G in the Jinhao can be made to work, the shortcomings mentioned in the comments and the article are real. It is difficult, and is, at best a "workaround".
I've developed an entire line of fountain pens entirely around the Zebra G using a proprietary, custom made (by me) ink feeder system that:
1. Handles the ink flow demands of the flex nib, and
2. Is easy to remove, reinsert, adjust and clean with a precise, smooth press fit with a hard stop. It's taken me years to get here, but it is about as fool-proof as you can get.
I have reviews and videos to show what you can do, and have four years of happy customers to show for it.

All of my pens can do this. Available here:

They're not $5, but they're handmade in America by me, and come backed with outstanding customer service, if I do say so myself.
An option you should consider.
