Well I was able to try out the z2 shaft for the wkend. I did this camparison to my lucasi wich is consider high squirt. I set the same shot for both shafts it was a nice cut shot in the corner pocket and put inside english (I consider more difficult being right handed). The result is truly amazing, it does not matter how much english I put on the cb, I could aim directly at the point in wich it should go in w/o english and no compinsation and it does every time. My lucasi would only make it with slight english not extreme unless I compinsated. I am happy with what I have and will stay with the lucasi for 2 reasons. I do not feel I need that much juice on my cb and IMO I like to shoot with 13mm. these shafts r 12.75. If I were a beginner and knew this I would have started with this style of shaft. BUT IF AINT BROKE DONT FIX IT!
