Flying Tiger fountain pen (F) [update]

A while ago I did a review of the Flying Tiger fountain pen with EF nib. This pen was actually a disappointment. At the same time I also bought a pink pen from Flying TIger. I was under the impression that this one also had an EF nib, but this turns out not to be the case now. The pink version has a fine nib (F). The fine nib is a world of difference compared to the extra fine nib. With the fine nib there are no problems with the ink flow, no false starting and a good writing performance. Actually, a pen manufacturer should know how difficult it is to make a good pen with EF nib, especially in the case of really budget-friendly pens. Maybe it would have been better for Flying Tiger to only market a fountain pen with a fine nib?
