Well, you have a 7000, which gives you lots of flexibility..
When I want to travel extra light... with my D7000
I carry
20 mm
50mm
and then believe or not,, an old 75-150 series E zoom,, a wonderful lens,, it gives you the flexibility when you want some reach. and a very compact zoom for the reach, and it is a 3.5 which is not bad since it is 3.5 thru its whole range! and only a 52 mm, when Nikon could make a compact zoom that had reach.
I cargo pants or shorts and throw the prime in one of the side pockets, and then wear a single small lens pouch for the small 75-150 zoom.
Ultra easy, ultra light weight.
