To be fair the two of you have been working together, if not friends with one another, for quite awhile as I understand it. Plus, looking at due to curiosity rather than full on scrutiny is a bit different. At least for me. It might be totally different for you, I wouldn't know. However, I'd say at least three people doing the reviewing and again, people with different ideas of balance and perhaps different levels of scrutiny.

I'm not saying it'd be easy to do, but it is doable.
