+1 for PVS and chabotc. When I'm walking around in the streets, my most favorite lens is the 35 1.4, since the 50 is a little bit to tight in my opinion and in termes of sharpness wide open its really really good. For the long end i'd go for the 85 1.2 II (higher budget option) because its more versatile than the 135 2.0 (lower budget option). Both are absolutely sharp wide open and have a super beautiful bokeh. The thing is: If you wanna do a portrait of just the upper part of the body, both are excellent, if you wanna get more in the picture and be more versatile, you can only do that with the 135 by yelling at your model. Until today I had skipped the 135 2.0, just because I own the 100L and the 70-200, so its a bit of an overkill for me, but I got a lot of overkill in my setup and right now I'm seriously considering buying one because it's just a great lens for the money!
About the wide end: I find the 35 1.4 to be a slight tick sharper than the 24 II (I compared various copies and hat a chat with other people who own both) so I ended up selling mine and I'm now considering the 24 TS-E as prime. At the wide end I'd go for nothing but the really outstanding 14 2.8 II since its one of the most interesting lenses canon has to offer and its way better than the zoom options. So my suggestion would be 14, 35, 85 and for everything above just the 70-200 2.8 II. Then you have a wide spreaded field of focal lengths with reasanable distance between each other. just my 2 cents
