HaroldWilson...What does that mean?...no stopping power.

Hi Scott,
By stopping power I believe they are referring to the amount of movement the white makes on a long straight or slightly off straight shot when striking the cue ball at medium to hard. For example, such as having the white near the bottom pocket on a snooker table and stunning dead straight long blues off of the spot.
This is a common practice routine and some cues will throw the white ball slightly off of the blue spot and others will be able to hold the white more consistently on the blue spot.when playing the identical stroke.
Of course this comes down to cueing as well as the shaft wood and construction and I have found the LD shafts on a pool table tend to throw the ball off more than a high end solid maple shaft.
I use a Black Boar with original shafts and also Vollmer shafts and have a Tad with excellent shaft wood and these cues perform better for me personally on these particular types of strokes than say a Predator shaft.
Similarly if you are playing lets say an 8.5 foot long stun shot in 'one pocket' with the white at the top of the table and have a ball close to the opponents pocket near the bottom cushion on a slight angle. If you wish to play a safety from that distance and stop the white ball dead or with very little movement as soon as it makes contact with the object ball I have found it a lot harder with LD shafts as they tend to throw the white ball slightly off.
Now to put this all into perspective, 'stopping power' is a term that the Taiwanese coach used and not one of my own but this is how I perceive the terminology. As such, I can understand why a coach would want there pupils to play with a particular type of cue which hits in a manner consistent to how the coach teaches cue ball control. If the coach is teaching a certain methodology and is expecting the ball to react in a certain manner then he is going to want the pupils to use similar equipment.
Lastly, I also understand that cueing has a lot to do with this and a good cueist would be able to do it with an LD shaft but the point I believe is that high quality solid shafts can play these types of shots with more consistent results. Likewise Predator shafts can play other shots better than solid maple shafts such as long screw backs IMHO.
Thus, each different type of shafts have there own benefits and different levels of performance. Likewise different cues have their own different levels of performance based on cues overall construction such as have steel or ivory joints etc etc. For example, I have been fortunate to spend a couple of days hitting with 30 odd high end custom cues from new and Predate Southwests, Searing, Black Boar etc and also owned a variety of SE and LE Predator cues and all of the cues had their own particular nuances when playing particular types of shots.
LASTLY

to cap this off. I have owed at least 10+ Predator cues in the past with 1st and second generation shafts and have also played with a lot of others. In my experience they are not the most consistent shaft built and the specifications are not always the same such as weight, balance etc. Thus, one shaft can hit quite differently from another of the same model.
Conversely, the quality management going into the high end custom solid maple shafts I have used tend to have a more constant hit and feel across the board than the production shafts. Some of them also have an almost identical pitch when striking the ball.
