I just ordered the 135L. I was debating about the 85 too, but I shoot a fair bit of indoor sports of kids and stuff, so the extra reach was the selling point for me. I've rented it a few times and absolutely loved it. It's a stunning lens.
I also rented the 70-200 f2.8IS. The zoom is no doubt very convenient, but it comes at a price. The lens is just plain too heavy for me and I know I wouldn't use it enough to justify the cost. I'm also not a fan of the white lenses, they just draw too much attention. If you use a 400mm it doesn't really matter, but I think the 70-200 would be better off black, in my opinion anyway.
I've also rented the 85 f1.8 (f1.2 is out of my price range too), I like it, but the 135L beats it hands down.
