Anyone used one? Im looking to get my ct upgrade done in the near future and I hear these are supposed to do a better job of holding the shaft steady than the stocker (and hopefully extending the life of the upgraded ct). I talked to PT today and they said the never used one and the stocker is good enough, and I also taked to other companies and they said its worth while. Any thoughts??? I havent seen this topic disscussed yet and I have searched, but if it has been disscussed please point me in the right direction. Thanks.
