A friend of mine has a jump cue shaft attached to an old Joss cue. The shaft has either a 14 or 15mm tip that is made of white/clear fiberous, phonolic, rock hard material. This is by far the best jump shaft I have ever used. I currently use the Bunjee Jump cue, but it still doesn't compare to this shaft. Any ideas who makes this shaft or where they can be purchased? Pleas help!!! ...Zim
