Hi. I love the nib on the Hero 329 old version, but really hate the rubber ink reservoir, it is annoying on a number of levels, and depending on the ink (noodler's bulletproof black in particular), it can be quite problematic at times. I was going to post a topic on whether the Hero 329 can be fitted with a slide/piston converter, but I figure that might too involved, if even possible at all. Instead, anyone knows whether there is a Hero pen with the same exact nib as the 329 old version, but which can take a converter? P.S. I read before that the new 329 is not as good as the old, then later I read that the issue is that the nib on the new version is much smaller, and hence scratchier, which is the reason I would rather avoid such a nib in any new pen I buy. Thanks for all suggestions.
