Oneye
I also made a ship to take out the ship from the video. It is one of the most ugly things I've made...

Ready Aim Fire
It is cheaper than Oneye's, but also less effective. There is the large luck factor of hitting the critical points, can take out a shield in one hit, and the shot keeps going afterwards.
Instead of charging at the target, it is actually so slow the kite cannot kite away. By strafing it will be able to get itself in a beneficial position. This way it is best against railgun only, almost unarmored kites.
