I suggest you read some info from http://www.wikisocion.org// (the static/dynamic stuff was not really a serious info to take into account, thats hard to set stuff in stone for this dichotomie. That was just an impression.), simple source organized like wikipedia.
At this moment from 2 last post my guess is most likely delta NF; I dont think you are Ni, and thats not for trolling current typing. But you should wait other opinion, Im not the boss of socionic typing
Because (and thats subject to debate but thats my opinion) 6 are most often ESI (ISFj) and EII (INFj), and thats said from various source that 6 is a Fi enneatype (wikisocion, some enneagram description, ect...).Also, how does 6w5 suggest no Fe?
