I have and still am working on upgrading my 5.2 My tiller bar has no slop at all. I used tiller extension mounts that have cord running through them in case the rubber breaks. My rudders are measured straight no toe in or out. Works great, I have the carbon adjustable tiller extension. I have 10 to 1 main with a smaller diameter sheet, runs easier. Attached a couple photos.
