Udvar-Hazy carrys more weight than Keesje but even he's commented on the lack of a/c designed for the 5,000-6,000 nm markets.
A plane designed to fly 8,000 nm that's flying 3,000-6,000 nm sectors is inefficient.
The question is where is the tradeoff between the two models? The market place seems to have chosen the larger a/c.
