I had my 19 when the new rudders first came out. I had set them about where the old rudders were. I sailed the boat and adjusted the mast rake from there. I built my main with a bit more draft up top, so I had a bit more power in the back end. I had built my own modified gudgeons. To keep a neutral helm with a touch of feel, you will need to customize your mast rake. The different sail makers have the mast rake about the same place, but it will depend on how you sail the boat. For example, are you one that pulls downhaul pretty early, or do you muscle through it? I had taken the cleats off the downhaul and the crew used to play the downhaul as the fine tune main adjustment.
