A basic tenet of aviation, is you are not supposed to (allowed to) use the trimmer as a primary flight control. It is only there to remove stick loads, after a manoeuvre has been completed. You can get yourself in a right Branston if you fly the trimmer, which is why most people would delay the use of trim.

The 737 speed-trim has undermined that basic tenet, because it is always placing the aircraft out of trim, but still there should be a considered delay before using the trimmer.
