It seems to be common knowledge that low deflection shafts achieve that benefit by reducing tip mass, through use of a thinner tip diameter, hollow shaft end, and shorter ferrule. My question is this: what difference does it make to use an engineered, spliced shaft on top of these other design details? Couldn't the same LD characteristics be obtained by using those same design attributes on a regular solid maple shaft? Why aren't cue makers going to shorter or no ferrules and hollowing out the last 3-4 inches of their shafts in order to get these LD benefits?
