Having built wheels for touring bikes I can say that it is not as easy as it looks to true a wheel. When a spoke on one side of the wheel is adjusted it affects the spoke(s) on the opposite side of the wheel as well. It is not difficult to find yourself chasing your tail. Minor adjustments are easy to make and likely to be more successful. Be careful as too much spoke tension can damage the rim and it could fail when your wife is on the bike.
