I always tend to give a bit of aft trim, the same trim position that keeps the nose-wheel light is the same position for a cruise climb so you transition nicely without having to re-trim.
As has been pointed out, we tend to teach to trim neutral as an exercise to get people to check the trimmer is not completely in the wrong position. When I check a new pilot out you can tell the experienced from the less experienced by the way the trim the aircraft (amongst other tell tales).
