I agree with your selection. I usually carry a 20-200 mm zoom lens, and a fixed wide-angle lens. I would like to get a fixed macro lens soon. I have gotten the impression that fixed lenses create better images then zoom lenses.
17-55 Nikkor for street-life, landscape, portret.
11-17 Tamron for street-life, landscape, some art-affects
70-300 VR for landscape, street life,
That's enough for all scenes I like.
But I want to buy a fishae, as 4-4/5nikkor (if I'm right).
I think it depends on what kind of photos you like. and your budget of course:-)
