Tough call. Millenial views are separate from views such as preterism, futurism, historicism, etc. So lumping millenial views with partial preterism is mixing apples and oranges. But if I had to choose one, I'd have to go with amil. However, I have a lot of postmil tendencies. I can agree with postmil up until a certain level. That is where they say that once the Kingdom has advanced and crushed all the other kingdoms, then the world will remain in that state for some long amount of time. But I don't find that concept to be Biblical. Paul says Christ must reign "until He has put all His enemies under His feet, the last enemy being death", 1Cor 15 something-or-other. So I stick with amil as a default option.
On the other hand, I am also a partial preterist (completely separate from my millenial belief). I believe that the events that were said would happen "soon", "at hand", "quickly", in "this generation" happened exactly that way. Jerusalem and the Temple were destroyed, the Old Covenant economy was brought to a close, and the New Covenant was in full swing. And that all happened within the generation of the Apostles. But there were other things that did not have any kind of time indicators with them. Things that were to be in the future, but never "soon", or anything like that. For instance the resurrection. Christ said that there will be a day when it happens, but He didn't say it would be in "this generation" as He said Jerusalem's destruction would be. The judgement of the whole world (as opposed to this generation of Judeans) is another example. The Father has fixed a day on which He will judge the whole world. But He never said it would happen soon as He said other events would happen. Paul speaks of those things the same way. No time indicators. They will happen. Maybe soon, maybe in the distant future.
So that is where I stand.
