I forgot to mention i am also playing with Z3 shaft that i got from friend after my old Z2 ferrule gave up. He said: "it might be little warped" I told that´s fine i see if i can do something about it. He then come same tournament and bring me the shaft and i got 1st round game. Almost half of tip was missing and it was rock hard. Also I could hit ball behind corner with that shaft.
He said. "Oh it have been couple years in closet and got worse you don´t need pay that."
Anyways match start and i cold bend it while opponent make 1st rack and then i figure out how i need roll tip so i hit balls with good part of tip.
I got bad start because shaft not yet totally straight and tip is awful. I bend it more while opponent is shooting and people are like "wtf"
Anyways i end up winning match and after match i put Elkmaster on it and go and win tournament and beat guy in final who gave me shaft.
So i give him anyways 80€ from shaft and kept it. I play it still but I need do little straightening once a month.
