I'll second Mick's recommendation. I had a Photo Mechanic and Capture NX2 workflow for four years or so and it's a wonderful combination, primarily because Photo Mechanic is so fast and powerful. My workflow changed with Lightroom replacing Capture NX2, and Lightroom contains its own browser, so Photo Mechanic is no longer my "hub".
That said, I still use Photo Mechanic for initial triage, review, and sort It is simply faster than anything else. If on a client shoot, at that point from PM I export JPGs and create a quick web page for client review. ANd there are lots of other cool PM functions
