I've flown all of CAL's 737's, 757's, and 767's. They are all different. I rotate the 737-500 the same as the 737-900. The same with the 757-200 & 300. I rotate the 200 like the 300. The same goes for the 767-200 & 400. We also fly the longer planes with higher speeds on takeoff and landing to help avoid tail strikes. Many of my landings in the 757-300 are only 4 degrees pitch on landing. You can look up your takeoff and landing pitches in the FMS. If you get too close to the limit, a "pitch report" automatically prints out on the printer. I call it a report card.
