Hum... I loved the way the Conference'ish one looked, as it's a continuation of sort of a standard working itself into Zoner ships... just the cockpit needed more armour at the parts the pilot would't be able to propperly see.
As for the Virage...
A VHF, with less armour, slightly more power and (assumed) agility than the Eagle.
I'd say a nice adoption of the Zoner way of avoiding to get hit :D
