Mine will be the twins. My reasons are is that the twins can slow down any close range units. Another reason is that they can mess up others aim and have an amazing rate of fire dealing nice damage. Also since they have a good rate of fire they won't have to wait to charge. My first hull for M3 will be the hunter. The hunter is balanced, meaning it has a good amount of protection and speed.

I personally think freeze would win. 1: It can be upgraded at lower ranks meaning it can be effective even more earlier. 2: If you have a fast hull and freeze the opponent you can get away with it and have stung them and repeat over and over. 3: Just like 2, freeze people can be annoying and hard to hit. 4: Freeze upgrades are cheaper. 5: Last but not least offense really isn't a good path. This is my opinion, please respect it even if you got a problem with it. Although firebird is still also good.
