In part, I would disagree with that. The Ng wing weighs 5 tons more, but the aircraft cruises 20-30 knots faster, flies considerably higher, lifts more weight and uses less fuel. As far as the icing issue, yes, that should have been rectified at testing and is a pain for all operators particularly at this time of year. Also, the NG is slightly less speed stable on approach-the speed fluctuates whereas the Classic tends to hold it's trimmed speed better. A minor complaint but in gales or strong, gusty wind a Wind shear GA will be required more often.
