I'm also using Omnifocus but I do all my review using the review option within the system. However, I do set he project filter to each category in turn so I don't get distracted by things. I found it's best to review active project, making them inactive as required, then stalled, pending and on hold in sequence and just in case I make a final pass with remaining set to catch any that switched as I was doing review.
