I know that Rick recommends switching in a 10 hole adjuster and Harken makes a low profile 4:1 mainsheet for the Wave. The idea being to get more rake and load up the rudders. When you do that do you redrill the rudders to push them forward and minimize tiller pull? How much did you move yours?
You don't want to do any drilling until you get the mast and sail the way you want it. You can also get H17/18/20 upper arms that are adjustable. I asume you have the early style arms. The H17/18/20 arms are interchangeable and they are adjustable.
