Hi
The trimsetting is there for the event of enginefailure after V1, it will provide you with the closest trimsetting to v2 climb with one engine out.
That said, in my experience I rather like having to lift the nose for takeoff, rather than the stick forcing itself nose high, but then again that's a matter of prefferance i guess.
I generally suggest to keep positive forward pressure until rotation is desired, I feel it gives more positive control of the aircraft.
My thoughts anyway
