Regarding Crosswinds...
Used to do IOE on the 757/767, and always looked for a crosswind landing or two before sign off (very little emphasis in the sim program). One must be fairly aggressive with the controls during crosswind operations. The vertical stab is disproportionately large for the airframe (as it is on all of the heavy twins with wing mounted engines) to help keep the aircraft stabilized with loss of engine at low speed. That characteristic transfers into a rather sporty arrival in a stiff crosswind. The control forces are similar to those in a small/light aircraft in a crosswind.
Aggressive use of cross control on takeoff (up to roll spoiler deployment) is recommended. Great, great airplane, but it is quite the weathervane
