Ah, well I was just curious if anybody else has done this with their pens before, but have you guys ever modded or tweaked your pen with other pens? I have a Pilot Penmenship nib <ef> and 'guts' I guess you could say, but I found out you could use the Jinhao x750's body with it. I mostly did it because it gives it a good weight while I do my little sketches and such. Plus the metal body just feels better than the usual plastic. http://i1231.photobucket.com/albums/ee503/Zero1036/1206150058_zpsfm7mgwd7.jpg
