You got that Vidar fully equipped? It's a fantastic ship, it can see you through an awful lot, but I'd strongly suggest looking into getting yourself a M7. Some of the best choices for an all rounder M7 is the Shrike, Panther or Deimos, as they can all mount decent anti capital weaponry, decent anti fighter weapons and can also carry fighters. Some of the other M7s are also very good, but are more geared towards a certain task: the Tiger and Thresher are more like anti-capital Destroyers, with loads of IBL and PPC, but also can take quite a few FAAs, but can't take any fighters; the Cerberus is very good against fightets, as it carries a large amount of FAA, and a few fighters, but has almost no anti-capital weaponry; the Yokohama suffers from no real anti-cap weaponry, not many SCCs, no hanger and no purpose, it's very good at killing M6s, but so is your Vidar, so I wouldn't get a Yokohama. That's all the M7s you can buy, the rest you have to capture or are not availible in vanilla, so I wouldn't recommend any of them. You can then use your Vidar to escort any M7 you do get! Happy to help!
I will be the one to take you down!
