Fly Only With Trim?

Only one question: In a FBW Airbus how will you as pilot sense which way to trim?
Because in turbulence you want to preserve that trim setting which will cause the aricraft's positive longitudinal stability to get you back to a correct AoA. Several pilots here have said that simply letting go is the classic way to get out of a difficult situation, and that is true, but once the trim is changed, letting go is no longer an option. In fact, with the neutral longitudinal stability brought about by the autotrim (when hand flying) if you let go, the airplane will hold the existing pitch at one Gee and if it is nose up, you will either mush along or stall when you run out of kinetic energy. Several posters here have commented that the Bus has wonderful positive longitudinal stability. We should take advantage of it.
