How much
would a typical light twin pitch up on takeoff with the trim set like
that? I know myself, I usually ended up trimming down on climb because
the nose was hard to hold down (although I never flew the 76)

Then you started with too much nose up trim on takeoff. Every plane is
different. Go out and try it yourself with whatever you fly. Go up to
altitude and slow down as much as possiblein a takeoff configuration,
then roll in full nose up trim and go to full power. It'll get your
attention but you'll have no problem.
