In my experience, if you are much more than .25 in repo ratio VR doesn't really work well and you have more misses than hits due to the thin DOF. If you do go longer it gives you a lot more working room, and because the reproduction ratio is the same the only real change is more working room and light. I have the Nikon 200mm f/4 Macro and medical nikkor 120mm f/4.0 Macro with built in ring flash and they work perfectly with the X-Pro2 and provide a lot of working room.
While not stabilized I don't know if I could ever be talked into selling this setup, which is also one of the best product photography lenses I have ever owned.
I need to rebuild my real portfolio site but with the x-series focus highlighting I just set it to the view I want and adjust the distance for focus and it works great.
