"but, but... testing takes *time* and *money*! Why oh why won't someone just take me by the hand and show me exactly how/where they make their living?"
Seriously, every ad network has stuff that works and stuff that doesn't. As soon as you find 6 guys who hate AdBlade, you'll find a half dozen others who can bank with it. Even shitty AdBrite works with the right niches and campaigns, and that's saying something.
I hate to sound cliche, but the answer really is 'test for yourself'. Consider it an investment in the development of your skills and business. Even if you're 'losing' money, it's not for nothing if you're paying attention and learning something in the process. If you don't like to learn and/or just want easy money, good luck in any business. There's even a learning curve in slinging crack.
This is in no way intended to harp on the OP, it's just a general commentary on people asking if anyone's had any success with X Y or Z ad network. It's really a pointless question because no matter how many people say 'yeah, I'm banking with X', chances are you'll lose your ass with X until you figure out what works for *you* there.
