Python works well.
Big enough to pack a decent punch.
Small enough to not be considered an automatic Alpha Threat, and to run away when running away is called for.
I like fighting in the python, I really do, BUT I like fighting AGAINST pythons even more. They are so huge you just can't miss 'em. lol. I wouldn't take it to the CZ over the gunship or the FAS, or even a Vulture if I'm honest. But yeh, they have good runaway speed compared to some options (gunship is slow as crap), but they also have big bums, so are easily hit from behind while on the run.
I see big ships a lot in the low CZs, possibly even more than in high CZs for some reason. Maybe I just had weird luck. Makes me happy though, I like going big game hunting
Went into a low CZ the other day in my FAS. Only got to pop an Asp Scout before suddenly drawing simultaneous agro from a gunship (+SLF), a Corvette (+SLF), and an Eagle. Barely got out alive. Thrusters ended up taking a beating and started malfunctioning. I couldn't fly straight so I had to boost and turn FA off to drift out of there like an asteroid. Factor in the cost of repairs and PA ammo, I lost money on that venture. Fun though.
Yeh, I too find aggro is a bit of a mystery in low CZs at times, I tend to only bother with high these days.
