let's get something straight, if you want to play around with secondary flight controls instead of primary flight controls, fine
but do it by yourself without passengers.
And you should always be in trim. Always except perhaps in the last seconds of flare.
Muscle memory is fine, but if you are on final you should be able to let go of the control wheel and the plane remain where you left it in calm air.
I'd like to see those proponents of flaps as glidepath control do it on a normal FAA checkride . IF the examiner was generous he would let you do it again. If not, he would fail you and I would have such a good laugh.
