I was wondering if anyone knew if the pilot 78G calligraphy nib is the same nib that is in the pilot Prera? I was thinking of getting a 78g and swapping it into a Prera. I like writing with stubs and find the calligraphy nibs to be pretty close to a stub. I would appreciate anyones comparison of the two pens and their nibs.I have shied away from the less expensive Pilots because I am not sure that I would like their steel nibs. I love their 14K nibs but don't want to spend the money for a calligraphy nib for any of the other Pilots. I bought the Parallels and the Lamy Joys but would like a writing pen that has a calligraphy nib. Any suggestions would be greatly appreciated.
