I'd go for the M9 and pick up a good used D3 or even D2x (about $1,000 on Ebay). Add a 60 or 105 micro, a 70-200 (or 80-200) and 1.4 or 1.7 extender and that's all the Nikon you're likely to ever need. Forget the 17-35 as your Leica has those focal lengths covered. The weight and the speed of the brick-like Nikons come in handy when you're shooting fast and furious from a distance. With the zoom, it's a very steady 5 pounds. Sure, there not cameras you want to pack when going on vacation, but they are workhorses. They're okay wide but you know the M9 is going to be better and a M9 (or M8) with a 28 and 15 will weigh about the same as a 17-35.
