Tellin' it like it is...
I'm sure the ebony cue will hit harder ( equals delivering more power ), wont it ?
Please correct me if u beg to differ ?
Assuming hitting the same place on the cue ball, the only things that have any significant effect on the "power" (energy) delivered to the cue ball are:
-the weight of the cue
-the speed the cue is moving at the moment of impact with the cue ball
-and to a much lesser extent how hard the tip is (there is very little difference in the power transfer between leather tips within the range of hardness's most commonly used for playing though).
-and also probably to a small extent the stiffness of the shaft and the amount of mass in the front end, but again, any differences probably are too small to worry about in practical real life situations.
For practical purposes mostly what really matters is just the weight of the cue and the speed of the hit. The type of wood has essentially zero to do with "power" (how much energy is transferred into the cue ball).
What the type of wood can affect however is the type and amount of vibration (feedback) you will feel in your hand, and this vibration is a big part of what people call "feel" and terms such as "hard hitting" or "soft hit" are often used by people to describe it. So the type of wood can have an affect on the type of feedback (feel) you receive, and in that respect can be an important consideration in meeting your personal preferences for "feel", but it has no real effect on "power".
