Earl,

Interesting reminder...... For myself, I have found the following useful when operating my 320 at slower speeds (below 120 KIAS, 10 degrees or greater flaps to keep the nose down) - I find it necessary to max trim right rudder to keep the ball centered (the rudder itself is not full right, just the trim). And, a go around never requires full power as the prop is left in cruise pitch with the power advanced at a moderate pace until in positive climb. Flaps retracted to takeoff position with the gear left down and locked and pitch trim to match the flap position. After all, we are flying a slick airplane that is over powered by spam can standards (especially a 320 powered 235 or a 400 powered 360, let alone a 360 powered 360). A missed approach is slightly different as the airplane is cleaned up and the power advanced sufficiently for a climb at approach speed (approximately 120 KIAS). Wake up right foot!

I'm another 235/320 driver that added the ventral fin that extends the length of the rudder. I did not add the trailing edge full length.

So far, I've had enough rudder to maintain runway heading using the gradual throttle (as I too was taught many years ago). Use caution and apply rudder quickly on a go around as this caused an unwanted left turn recently.. I blame not paying attention...seeing the windscreen fill with tree tops brought me back to reality!

I did as Gary described but also added 3" to the trailing edge of the rudder full length.
I can nail the power on take off and have no trouble keeping the airplane heading down the center line.
FWIW,
I was taught to add power gradually which I do, usually anyway...
