Don't spend too much money: in a A graded Vulture, no NPC will really be a threat. I make more than 2 millions per hour and only go out when tired. I'm there without a single SCB and when I'm out of chaffs, I'm just a little more careful around elite anacondas as they tend to pack some punch. SCBs won't do you good if you want to endure over time. Instead, get an A0 shield booster, military grade (or mirrored SC) plates and a D4 hull reinforcement. You'll be surprised to see how long you can fight without a shield, should it go down. You're fighting AI, not vicious players. Also, get an A grade life support system, if you can. A Vulture canopy is made of recycled grocery bags plastic. It *will* break first.
I frequently get teamed by two or three ships, incuding annies and pythons combos, and can't even sweat for the sake of it. I'm just careful about their ranks when it happens and even then only Condas and a few harassing pythons can represent a substantial danger. For anacondas, competent to master, you can walk on them. Expert, deadly, dangerous means focus a bit, elite means, well, focus a bit more. If they really are after me, I never hesitate to run away a bit and eliminate the pursuers if any.
The only time I was forced to bail out and come back was the well done job of an Asp. Those guys are equipped with rails, and use them extensively and accurately. He broke my canopy and since I had a crappy life support, I had to repair ASAP.
