Yeah, I can play with a broomstick, but most people paying $500 for a LD CF shaft may want to take the game a little bit more seriously than that.
If you have to change all of your "form" to play at the cue's pivot point, it is more of a hindrance than an attribute.
For example:
I have around a 10-12" bridge.
The front of my grip hand is around 3" below the top of the wrap.
When I am leaned over the table for a "normal" shot, this is where most cues feel balanced to me.
In "that" stance, my eyes and body have learned that is what works best and has been engrained into my visual and muscle memory.
If I would go to a cue that required me to bridge the cue several inches back at another pivot point that would:
Make me have to grip further back in order to make the cue feel the same balance.
Make me have to adjust my stance at the table because to keep the tip at the same distance from the cue ball when stroking, I would have to be further back from the table.
It would change my angle of sight when bent over the cue and looking down the shaft.
Anything can be learned if you put enough time into it, but changing things to keep up with fads should be left to people who are actually making money playing pool and who are getting stuff for free from their sponsors.
I have played for many decades and have thousands and thousands of hours on the table and have HAMB.
I have HD, LD, wood and carbon fiber shafts and I never change anything except my aiming point. I know where the cue ball is going to go when I shoot.
