I honestly do not know what the stigma is with fighting somewhere other than on the deck. I have had some great tangles lately by climbing to 20k or more. It's a whole new ball game up there. I suppose the derision comes from those that pick and return to the heavens. Well they ain't picking if you go up and challenge em! 
that's why i went up there. it seemed to me, that no matter where i furballed, these people were up there, and it seemed that i was always on the recieving end of their guns. so i went higher than they were, kept in constant communication with friendlies in the area, that kept me updated on the location, and alt of the red aircraft, and set em up. they dint like it.

and yes, i've had some great fights up there.....but fighting down low is faster into the fight, which i prefer.
