A minor consideration was already having the 300 II and wanting more separation b/t it and a super T.
This was a consideration for me as well (though I have the old 300mm). I wanted a lens that would get me closer than the 300 f/2.8 with extender.
I have the 600 II and I am very happy with it. I use it with the 1.4xIII extender most of the time. If you´re not used to long lenses, you´ll be surprised to how many times you´ll say 840mm isn´t enough.
Yes. This has been my experience as well.
For me, the weight/size difference between the lenses (and the Sigmonster and similar) were not significant. There's no way I'm using any of them without some kind of support, so that wasn't really an issue. If you're a big strong guy who can hand-hold a 500mm, it might be different.
