Hi UNCTUOUS.
You are right about reverse pitch moment.
Geometrically the pivot are the main wheels, but being a dinamic scenario, the cg of the whole thing still remains above low mounted engines.
Point taken.

Now, back to main topic: is it true or not that spoilers kill only a fraction of the residual lift?
Is it true or not that we can change our pitch by yoke input during rollout?

Mad (Flt) Scientist,
It would be great if you have the (approximate) figures: what percentage of total lift do the spoilers kill after touchdown?
How much residual lift is killed by a pitch reduction of, say, two degrees?
Is the net result outweighing the lift created by down elevator?
