I was expecting a significant amount of feedback but it just wasn't enjoyable at all. The ink flow seemed poor, which made me think I was doing something wrong. I tried it on Tomoe River, MD, and Clairefontaine, but didn't like it on any of them. Maybe I'll stick with Pilot & Platinum ...

All I can suggest is maybe giving it a flushing with water, and trying again. Or else checking nib alignment - if its slit isn't directly over the feed slit, you can have flow problems.
