I have just purchased a slightly used Excal II with the standard "S" shaft. Since I already have a GT, I know all about the weight. I need some advice on which is the preferred shaft and or rear shaft attachment. I don't want to keep buying different shafts, but would rather use the knowledge and advice of this forum. After all, who knows best, but you guys. Please send some advice. I'm heading to Melbourne, Florida on the 11th and want to have this all together by then. Thanks.
