Eve Online: Exploration (Heron, Retri)

I ventured (pun intended) to lowsec with my Retribution and Heron, built a Heron for Data sites with proper rigs, but then I had to attack with my Retribution, which only worked on some smaller entities which were warp disrupting me. I barely escaped by complete luck and ignorance of the danger level I was in. Next time I will stay near Highsec until my skills are finished. I need something like a battle ship to fight this many. Especially alone, in my personal "fleet" of ships (alone).
