I made a Royal Quickdraw some time ago. The XL is more vulnerable than the Light Engine, of course. But with the Artemis supported LRM and the ER Larger it has good long range firepower, and the SRM and the Medium Pulse Lasers also deliver precise firepower at close-range. It's main weakness is that it isn't jump capable anymore.
