Might depend on your approach profile as well. Trimmed for optimal forces during the flare may be the very close to the trimming required on a shallow (IFR-like) approach. But if I deploy landing flaps and cut the throttle only when I am sure I reach the threshold, then I must "dive" to the runway and that requires significant forward pressure till round-out. I won't trim this out, otherwise I will have to pull hard on during the flare.
I had this topic discussed with one of my instructors. He advised me to keep pushing the stick during the last part of the approach, because it's a relatively short part of a VFR approach, and the light forces after round-out are more important. However he mentioned that tow planes have a much longer steep descents, and they have to trim their elevator to that. Which addmittedly requires a great deal of struggle with controls during and after the round-out.
