My technique for flying real smooth: put the autopilot in!
That's good point on maintain 1G on maneuver.
Any lateral manoeuvring ie turning must be accompanied by more than 1G, otherwise the nose will drop (unless you happen to want to descend at the same time). So when you start to turn, pull (ease!) back the stick, and trim if necessary, or if in one of them plastic Bus thingees...I dunno!
I "lean" on the control column/stick; don't jerk or yank it.
