it is copied from the 147 club.
i do think it is helpful, so i post it here.
hope it helps

I thought I'd add a few technical comments to this discussion, from
the
perspective of a cuemaker.
If you look at the mechanical properties of the two woods (Hard Maple,
and Ash) the stiffness is determined by the Modulus of Elasticity (a
common engineering term).
In general, Maple has a slightly higher MoE than Ash. However, this is
an average figure.
It is possible to find individual pieces of ash that are stiffer than
individual pieces of maple, and vice versa. So it's really a per
individual cue issue.
Ash is slightly lighter (less dense) than maple. So in aerospace
terms,
ash has a slightly higher Specific Modulus (stiffness per unit mass).
This can mean that the dynamic stiffness (how the shaft vibrates when
set into motion) can be slightly higher in ash than with maple. Thus,
even though two shafts of identical taper dimensions, (made from ash
and
maple), and static stiffness (how much the shaft would bend, or
deflect
under a fixed load) should in theory behave the same, in actual
practice, the ash shaft can "appear" to be stiffer. (it
would damp out
faster after starting a vibration).
What does all this mean for playability?
Not much, I'm afraid.
You really have to hit balls with each and every cue that you want to
purchase to make a determination.
Certainly, the two woods make a bit of a different sound. I find maple
to be a bit "quieter" than ash.
Another factor is availability. If you can find a large number of
either
types of cues locally to test from, then it really shouldn't matter
what
wood you choose.
But often this is not the case.
Here is Canada, it is easier to find maple cues of high quality. Thus,
with a large number of maple cues to choose from, it is easy to find a
superior cue for top play.
But the reverse might be the case in the U.K.
If so, then I would recommend ash.
I think that it is possible to find world class cues in either
material.
But it might be easier to find one or the other near where you are
located.
I hope this helps,

If I find one in China I will buy u one la
To me I found Ash is good in positional play and Maple is good for power shot and long shot.

Copy from the Book "Know The Game - Snooker", A & C Black.London.
Bar Code of the book "9 780713 652659"...hehe
Page 7, Third Paragraph:
The most popular material for the shaft of the cue is straight-grained ash. The grain should not be too wide: about ten grain lines to the inch (four to the centimetre) looks good and is sufficient to promote the required shaft strength. Maple is also a perfectly good material, but because of its density it does tend to push the cue ball off the intended line when 'side' is applied. In my experience a cue tip size of 0.38in (9.75 mm) allows the ball to hold its intended line more accurately. (The tip size required also depends on the actual stress strength of the particular piece of timber used in the cue.)
