Most wing-heavy conditions can be cured that way, rather than adding additional drag in the form of a trim tab. Also, check the aileron free-play. I believe it's supposed to be less than 3/16" with the balance weights absent (they usually are). Knocking it down to 1/8" or less with the yokes locked, and then removing any free-play in the aileron bell-cranks seems to work wonders in the 'fly straight' department. A properly rigged coupe on a calm day will continue straight for miles with two equal-weight souls on board. Otherwise, it will commence a slow turn to the 'heavy' side which the weight of a single hand on the side of the yoke opposite the turn just about corrects. My experiences suggests that, with 100 hours of annual flying, 'perfect rigging' lasts two years if you're lucky.
