Are you looking at new machines because if you are the 130 and new T2 is like chalk and cheese which means answering your questions using the 130 will have no relevance. The T2 much faster due much lower vibration levels due the new system. T2 much more power due Arriel 2D and 950shp MGB instead of current 350 750shp box. Much improoved aircon system with a environmental control added. Lower operating cost due much higher TBO on the Arriel 2D.
