Gnosis, Jack of all trades or waste of ISK

I know. What you are saying to an extent is true but that is earlier but now I am pretty experienced (mostly lucky). I know the disadvantage but if you consider that if I get 10 data containers, I may destroy only 3 or 4 of them and the rest gives me a loot of 20 million or 15 million and last time I have hacked 5 containers out of 6 and generated a loot of 10 million. C1 Wormholes are safe and they are not mostly found. I get mostly C2 Wormholes and the sites contain sleepers and I want to execute them without wasting time on finding C1 wormholes and after all this topic is about can Gnosis tackle the sleepers without getting destroyed and can generate maximum DPS or not.
