Tractor beams have a rather short range, so anything other than Standard mounts are a waste. Generally, you just want to be able to drag your enemy about 3 squares closer for Ripper Beams.
Note that with Repulsors, the ships will all move at the conclusion of your movement so that your other weapons can hit them (I only play Simultaneous mode). You will see all repulsed ships sudden jump positions at the end of your turn in the replay.
I am not sure if I would recommend using multiple repulsors as I doubt that Multi-tracking will work properly. You may hit the same ship with multiple repulsors.
Thanks, that explains it. I'm using the non updated 1.02 Version . I started playing as soon as I got it and now I'm in the middle of a game so I can't patch.
