I only have three: 35 f/2, 16 f/1.4 and 55-200. I do a lot of street shooting and a fair amount of landscape/architecture, but rarely need telephoto, so I went a bit cheaper on the latter and put my money into the wide end instead. I did have the 90 f/2 for a while, but as I don't do much portraits and tend to use available light the lack of OIS really grated, and it felt a bit specialised for what I was using it for.
