Is it possible to run 2 ad networks..
Such as Admob banners with Leadbolt notifications, since they are doing two totally different methods?
Hope you don't mind if I chime in here
Yes, you can certainly use more than one SDK (network) for ad serving. The only potential drawback could be a slowed performance of the app - although this is not a common occurrence.
It may still prove beneficial to run the one comprehensive network SDK that provides all types of ad units. However, as long as the app's performance isn't affected, then running complementary ad types is always encouraged.
