the idea has merit, I would suggest the elimination of puffy ack and the high wind thing not so low. 10K might be good as a margin. by keeping the bases close by I don't believe anyone will climb above 5k anyway. that was the one thing I liked about okinawa in AHI. the combatative bases were basically in the same sector and all the fights were low. also keep in mind that if you enable the whole plane set and the ceiling being so low it will be the spitty,niki,lala arena. the usaaf, most raf and luftweenies need a little alt to be competetive. some of the cartoon stars might do well in the 109F4 in that environment the rest of us would just remain in the MA.
