I've been trying this out since I read this thread, with great results.
One thing that did take me by surprise though was going against another pyra which I can only assume was using the same technique, given it's speed. They began to beeline towards us, so I killed the engines and switched over to moonshine to prevent us spinning away, only to have not only our hull armour totally destroyed, but also our health. Insta-death!
Not sure if this was just unfortunate circumstances or moonshine vs. moonshine creates some sort of force deadlock causing more damage... more testing needed!
