Thanks to all who have responded. Many very good points have been made. I'm going with the 70-200 f4L IS to take care of the longer focal lengths, the 100 f2.8L IS for macro/portrait, the 17-40 f4L and the 24 f1.4L for wide angle/landscape. On longer hikes where weight is a big concern, I will only take the 17-40 and 24 f1.4. I appreciate all of your insights and comments.
Hi, if you are really into landscapes, the 17-40 f4 is disappointing. OK, it is cheap and very versatile but that's all. The corners are quite soft and lack resolution. The same is also true for the slightly better 16-35 f2.8 in my experience. The 24mm f1.4 would be a waste of money and effort IMHO. If you like the shallow depth of field, get the 35mm f1.4 or 35mm f2 IS instead. 35mm is a much better focal length for street photogrpahy.
I prefer the TS-E 24 L II for landscapes. The resolution is much better than the zooms and wider angles can easily be stiched together. The optics are probably the best wide angle you can get for a Canon body. The shift and/or tilt mechanism is used in almost all my landscape photos. I use 24mm in about 60-70% of my landscape shots, 35-50 mm for about 20-30% of all shots and 70-100 mm for the rest.
