I really like researching and hacking...

I'm currently Vygoid Hacker

What should I go for?

Kronyn Explorer

or

Kronyn Hacker

or

Zolazin Spy

or

Zolazin Explorer

or

Zolazin Hacker

or

Zolazin Saboteur

or something else?

Zolazin Spy works well for hacking. Better than explorer, and better than hacker. (the 40 and 20% boosts are multiplied, giving a multiplier of 1.68. -40% for zolazin and you get 1.28 multiplier, which is higher than the 25% hacking boost.) You may consider saboteur though for the ability.

Kronyn Explorer will do you well, as the explorer boost allows you to find VM planets to raise with the ability easier.

So Zolazin Spy, Kronyn Explorer, or Zolazin Saboteur.

Zolazin sab helps your legion and yourself take good planets. It's what i am, And I don't plan on changing any time soon.

Thanks for the replys! I think I'm going for Zolazin Sab or Spy
