Alan,as with anything not every nib will be perfect right out of the box and might need minor tuning. The nibs that are giving you a problem should write well just need a minor tune. Do you have a loop or small magnifying glass? If so look at the nib straight on making sure both tines are perfectly lined up., that the nib sits on the feed equal on both sides of the wings. That the slit from the from the gulp hole to the tip tapers and is not too wide (allowing the ink to flood). ?In the library Lou has a write up called you can tune a nib but you can't tune a tuna or something like that, it will give some basics. Remember all nibs are thin pieces of metal and during handling stuff happens it's just the nibs from companies like Bock,JoWo and a few other small manufactures in Germany are just made with much closer tolerances and are smoother plated giving a much better flow to begin with.
Thanks Roy, the information does help some on the history.
I have some Heritage nibs I got from Exotic blanks and have some trouble with one or two of them, so I'm still trying to figure out why one upgrade nib works better than another.
