I have used extensively this lens with TC's (all 3, from 1.4 to 2.0, just waiting my new TC2III).
All Tc's reduce IQ, so be aware of that, the bigger the worst (Arthur Morris suggest a 10% loss with a 1.4 and a loss of 28% with the 2).
1.7 and 2 will need good light to be able to focus at all. Expect a slower focusing lens.
Tripod, at least for me, is mandatory with any TC, even with a naked 500, if I want a professional sharp photo.
Not a lens issue with Nikon, the TC's have same sample variation, so try two at least.
On static subjects with little wind, even with stacked TC's (I know I'm crazy) I can produce some really goods photos. With movement things get worse, and in flight forget, at least with 1.7TC.
Here's my main setup with these TC's:
1.4 open or 1 stop
1.7 at least 1 stop
2 always 1 1/2 stop, the ore the better (light would be the problem)
Crank your ISO, because I prefer same noise to blurred photos.
Regarding VR I got a mix feeling, but normally is turned off.
