If you like the ER and scimitar winglets, wait until the MAX comes out. Boeing wants a bigger fan, but doesn't want longer main gear because of more wing redesign work and common type rating issues.
Their brilliant "solution" is to extend the nose gear several inches, which also helps get the front of the nacelles a few more inches off the ground. So then, you not only have tail strike problems, you have landing nose gear first problems. Your allowable pitch window for landing goes way down.
Should be fun in turbulence/crosswind.
Dreaming of Fifi, especially the new 321's with big motors..............
