I immediately took to the shaft when I first tried it 5 years ago. I even gambled a decent sized game on my way home from the place I bought it. I lost but it was NOT because of the new shaft

I was a low C player then, so I didn't know too much. I did know about deflection and compensating for it. I just noticed I made the balls much better than before when using english.
One thing I notice now is that for full or almost full hits on the object ball, there is hardly any deflection with the predator. I can aim almost as if using center ball. But a shot the same distance and speed but with a half ball hit or less will deflect much more and I have to then make quite a bit of aim adjustment.
Try the following shot. This is the one I always use when testing a cue for deflection. Shoot it with your cue until you've mastered it then try it with the predator until you have mastered it once again.
Copy the following code and paste it into the
RSB Table to see the shots (click OK if any security stuff pops up when pasting the code):
START(
%AI6K8%PX2T8%UK0M0%VW6T2%WQ5C9%XC5I0%YD3E0%ZI2K1%[D1I5%\I5K7
%]q8T0%^R4C8%eD0a0
)END
The following shot is the one that is a full hit that can get you in trouble. I have shot this many times and followed the cue ball right into the pocket because I was expecting the predator to deflect slightly but it did not at all. The cue ball is supposed to go two rails and out.
START(
%AF3Z9%P^4U6%UG5Z8%V]7U9%WD6[2%XF8Z9%YD1Z4%ZE7[3%[J1V6%\C4Y8
%eC6`8
)END
I have just switched to the Z shaft about a week ago incidentally from a regular predator shaft. I notice it deflects just slightly less than the regular predator shaft. I could play with it right away with no problems. So if you already play with a predator, the Z should be an easy change for you (based on my experience of course).
