If I could go back in time and change something when I was still learning pool,
it would be to invest in one of these shafts. You're going to get some people telling
you it's a waste, or it isn't necessary at your current skill level. This isn't correct.
Here's why.
First - understand what you're really buying. The shaft reduces deflection on moderate to heavy spin shots.
This will change your line of aim on those shots. That's it.
You're buying a different line of aim.
You're not buying extra spin, perfect draw, better cueball control, more 'finesse', and so on.
That stuff's all wishful thinking. The shaft is ONLY changing where you aim spin shots.
So why is buying a different line of aim useful for an APA 5?
• With a high deflection shaft, some shots look really weird if you have to hit them with lots of spin.
For example you'd normally hit the left side of an object ball if you're cutting it to the right.
But if you load up with tons of inside english, you may need to aim to hit the ball full in the face
(like a straight in shot), or even aim slightly to the right side of the ball.
Even if you hit this shot for the next ten years, aiming to hit the wrong side of the ball
will never quite look normal or natural. Your brain WANTS to aim at the left side of that ball.
With the low deflection shaft you won't need to compensate so much.
You can actually aim almost the way you would without english.
This greatly cuts down the confusion and frustration of hitting those heavy spin shots.
You can hit the ball with a little more confidence because your eyes aren't sending signals
to your brain like "WTF man this doesn't look right at all".
• When you get the new shaft you must relearn your line of aim for these shots.
So why spend the next 2-5 years learning a line of aim that compensates for deflection,
then buy the LD shaft and have several years of 'incorrect' aiming lines burned into your memory?
It will just make it harder to adjust. You don't need to be an APA7/9 to get the benefit of an LD shaft.
If anything, I think it helps a 5 more than a 9.
Don't learn how to aim the shot with cue "A" if you are definitely planning to use cue "B".
That's like preparing for a drag race by driving a pickup truck.
Sorry for the longwinded reply, lemme actually answer your question now:
I've used all the shafts mentioned and I slightly prefer the OB's, the OB2 and Classic Pro.
But the differences are small. I could pick up a Z2 tomorrow and play just fine. They don't play wildly different.
In fact, most players could not pass a "pepsi challenge" and hit balls blindfolded and tell you which
shaft is which. So don't sweat it too much. If I had to recommend just one, probably a classic pro.
A few people complain the OB2 feels kind of soft and mushy to them. I never heard complaints
about the classic pro.
