Hi,
I would like to know who have this shafts and can make a comparison about both shafts, it´s more difficult Z2 with side spin?, it´s true that you must to shoot precisely in the center of the CB because if you move a little the shaft the spin increase a lot?
thanks.
I have both of these shafts, but it's clearly not for everyone, as you can see by the results from my survey thread here:
http://forums.azbilliards.com/showthread.php?t=66887. The 11.75 mm responses are most likely Z shafts. So only about 5% of the respondants reported using this shaft (as of the results today).
I have played with these shafts for a couple of years now and am pretty comfortable with them. I would say the strength of these shafts is that you can shoot a long shot with outside or inside english and aim almost exactly at the ghost ball target next to the object ball (in other words you don't need to adjust over an aditional amount to allow for squirt/deflection).
Yes, placement of the tip on the CB is very critical, and you will see the effect of subtle differences in tip placement magnified on your shot. If I'm in stroke, this is good, and I feel that I can really control where the CB is going in order to get shape for my next shot. However, on the nights where I am off my game, this can be a nitemare. Also, if you elevate your cue at all the effect is magnified. Again, you can use this to your advantage for masse and swerve shots.
I'm not sure I agree with Steve about compensating for english induced throw. Yes, you can cause this effect on purpose if you wanted, but I usually don't find myself making it happen that much (if at all) in my game. In fact, I could take off all the throw on a shot (whether collision or english induced) by using the appropriate english (e.g. outside english on a cut shot). I find myself doing that alot, but you can do that with any cue.
Now you might want to leverage this capability (using sidespin to throw a ball) but that's to be decided by you on a shot by shot basis. I can use side spin to throw a ball in a pocket using minimal forward roll, to keep the CB from traveling very far after contact. Or, I can make some long thin cuts go for a walk along the rail (both with inside and outside english). I think without the Z shaft, I would have to completely learn these shots (especially the outside english one). All of this you can do with any cue, but I have learned how to do it easily with the Z shaft(s).
I don't notice much of a difference between the two Z shafts, but there is a measurable difference in deflection. I did look to see which one I had on the other day after I had barely missed a couple of long thin cuts in a game. It turned out I was using the Z and not the Z^2 (I had been at the billiard shop earlier in the day measuring the tip diameters and I put the shafts in the opposite slots in my case; so I grabbed the wrong one when I was playing). Of course, that may not be why I missed the shots
I also have a 314^2 shaft (12.75 mm) and two 13 mm Tim Scruggs shafts (originals that came with my cue). I can play decent with all of them. I would say that the larger diameter shafts are a bit more forgiving on miniscule aiming errors. However, I feel that I have learned a few "tricks" with the Z shafts that I can't do with the others. Right now, I am practicing a lot with the 314 and TS shafts to see if I can get to the same comfort level that I have with the Z's. I may be working my game back towards using the more convential shafts.
Of course all of this is MHO, YMMV.
