I try to keep multiple ad sources running at all times, but give most views to the highest CPM source. I've made some major shifts when Adsense or another ad network starts running consistently low. These things seem to cycle as advertisers come in and out, budgets run out or get renewed, etc.

Sometimes, of course, these moves don't "scale up" the way you'd like. A great eCPM at 10K exposures per day may end up considerably lower at 200K exposures. So, keep monitoring and tweaking.
