Best Adbrite Strategy?

OK.. adbrite is set up.. I have standard placements set.. a couple InVideos ad spots.. been about a week and now I have 120 ads to approve (I set to approve).
What’s the best strategy here.. only approve high CPM ads? approve as many ads as are appropriate? Select 5.. see how they go.. kill em.. select another 5 see how they go? Just wondering if anyone has had any experience optimizing revenue from Adbrite ads.
Should I just set the "auto approve" and let the network decide which ads run (seems like a bad idea cause there is some crap in there).
Any help would be great.
