Taildragger67,
I'm also not trying to start an Airbus/Boeing slagfest but modern Boeings do have tailstrike protection. The 777 will protect you, however, if you really want to leave your mark on the tarmac you can just keep pulling to over-ride it. The 767/747's are pretty old technology now. Correct me if I'm wrong but both were designed in the 70's/ early 80's. The 777 and no doubt the 787 offer full flight envelope protection but the pilot always has the option to over-ride it simply with control/thrust lever inputs.
