Realizing the question was directed at Ben, I’m going to jump in here and give my two cents.

Any airplane will climb when power is added, if the cg is ahead of the neutral point (it has positive pitch stability). If the climb is excessive it always indicates that the cg is too far forward. The fix is always to move the cg rearward. Changing the wing incidence will not affect the tendency to climb with added power if the cg is not changed. It will only affect the trim position in level flight.

There is only one power setting at which the trim will be zero. Faster flight will require down trim while slower flight will require up trim. Typically I trim for about half throttle which is the basic power setting about which I fly, then use elevator to adjust for power changes. But that’s just a personal preference. For an airplane to fly “groovy” (that is to say just go where it’s pointed) at various power settings requires balance at or very close to the neutral point.
