737NG
It is true that the 737NG is certainly not the best Boeing and regarding the wing,there is this NEI problem but one point really strange are the landing speeds(VREF) much too high for a short/medium haul a/c.
For the 737-800 at 65T(MLW) FL40: 141Kts
FL30: 148Kts
And the wing is much bigger(span& chord) than the previous models!
Compare to the 757 I flew before it is higher and also the 757 brakes are much more efficient.
Boeing should have built a small 757 or a small 777.
It is nice to have same rating as the old series I flew also in the past but there is a moment when we have to stop doing"new" model with "old" one.
Happy landings!
