It is true.. you really have to remember that before you rotate... if you pull as hard as you do on the 757 when you're flying a 767, it could conceivably be very easy to tailstrike.
The 767 is very much a finger tip flying airplane... to the point of being a bit twitchy, even.
The 767-300 is a very power on landing. When you want to touch down, you pull the power out. In the 757-200, I have the power idle at 30 feet and start my flare at the same time.
That being said, at DL we have blended pay for the 757-200 and 767-300. I am in the domestic category and fly mostly 757's with a few 767's sprinked in. My next trip, the first leg is a 76, then 2 legs in the 75... layover...and a 76 redeye to finish up.
