I love it, I really love it! I'd be flying this in dogfights all the time, loaded up with Piranhas.
While I adore the offset gun mounts, I do really think it could afford to have another gun in the nose. Have the tech fluff (or even the table entry) note that the triple gun mounts are meant for Maxims, Akhetons, or tactical weapons. Like the Ursa, it would be useless for dogfighting without them. Compensate with low weapons energy capacity if you must.
