I decided to swap the Medium nib from Custom 74 & the Fine-medium (FM) nib from Custom Heritage 91. This has been discussed at length before, as many Pilot models use the same size #5 gold nibs. My question is whether the feeds should stay with their original grip sections or go with the original nibs.
I understand that in theory the feeds should be identical (and they do look identical), but they do feel a little different when mated to the other nibs & grip sections. Is it possible to generalize on what would be the best approach? Are feeds & grip sections individually mated or are feeds and nibs or does it all depend?
