I would lose some landscape shots, but I would always use the 17-55 for that and on the other end it gives me more reach than the 85. Plus I would have the f/4 in the ranges I think I would want it.
• EF 70-200mm f/4L IS – For the longer reach. I love this lens so far.

A couple of points:
  • I am not sure weather sealing should be part of the consideration since your 60D is not weather sealed that well. With my 7D and its weather sealing, I may rethink that (for my type of shooting), but that is not the case for the 60D because the camera is limiting.
  • I do not think I would have the 17-55 and the 24-105. There is to much over lap, and between the two the 17-55 is the best lens for the croped body and the weather sealing (or lack of) better matches your 60D.
  • The f/2.8 on the 17-55 would allow you to start exploring shallow DOF and opens up some good oppertunities for you.
  • The 24-105 is better suited for FF if you plan on going that way in the very near future... then the 17-55 does not make a lot of sense.
  • I would replace the 24-105 with a 100mm f/2.8L IS Macro. This lens would open so many more possibilities for you and gives you a fast lens in the 100mm range, and it is really really sharp. I have the 25-105 and the 100 Macro, but if I had the 17-55 and no plans for FF, then the 25-105 would go. Also, the f/2.8 on the 100mm lets you futher explore shallow DOF (even more than the 17-55).
