It's ultimately your decision...but you'll get lots of experiences and ideas from what others here have gone through.
If it were me and I knew that they were looking to DF me and I had no real ties to the organization (like family) I would just refuse to meet with the elders. If they choose to DF or announce me as DAd, fine, do whatever. At this point, I would no longer give them any authority over me or my life. By agreeing to meet with them or discuss anything them still gives them a semblance of authority.
Some might say that you could make your stand and try to "debate" issues with them, but they have closed ears, they won't hear a thing you say. By refusing to give them the oppurtunity to lord it over you speaks volumes more than trying to argue with them.
All of this would change if I had JW family and was trying to keep my relationship with them intact. Depending on the seriousness of the "sin", if I wanted to avoid being DFd for that reason, some acting and lying would have to be used to fool them into thinking that I was repentant. After the Public Reproval was announced then could start my "fade" away from the "truth". Depending on how involved one's family is in the "truth" can make a difference as to how succesful that avenue would be.
