Today I found a competent anaconda in one of the anarchy systems I bounty hunt in. It had a 35k bounty on it (which seemed low to me. I remember seeing much higher).
I have a mostly A rating viper, with 2 small beams, and 2 medium multi-cannons. I don't have chaff. Instead I have a defense turret which was not helpful in this encounter. Second utility hard point has the kill warrant scanner which I need to hunt in anarchy systems,
The hardest part for me was staying on its tail. The Anaconda would constantly flip over and try to get its nose on me. I would boost out and realign, pew pew pew, boost out and realign. I got its shields down and went for its power reactor. By the time I got its power reactor down to 25% I had run out of shield cells, so I boosted away and diverted power to shields to recoup. The anaconda regened its shields, and I used my beams from 3k to slowly wittle it down while I struggeled to weave around its fire even from that distance.
Then I rushed in, guns blazing, my shields going down as I aligned behind it and took it out. Only lost 6% hull.
I'm going to watch the video posted here again because there's a lot I can learn from it.
