Canon 85 1.2L II

So I'm trying to decide on what lens I would like to get for my 5D Mark II next. I am debating on getting an 85 1.2L II while it is still on sale. The only problem is for the amount of money that I would be spending on the 85 I could get several other lenses that would be almost as good from what I've been looking at. The other lenses I have been considering are the 50 1.4, 85 1.8, and the 100 2.8L Macro. I already own a 50 1.8 and a 24-70 which can do some macro work and I plan to start doing some more portrait work. Any recommendations would be helpful.
