This is something I'm in total agreement with and is pure gold.

"I am not a cue-maker or even a good player, but I am an engineer. If you don't mind an engineer thinking out loud for a second, I will offer this.
The role of the threaded pin (no matter what style, size, or thread count) is to snug the shaft against the butt tightly to simulate a single piece of wood.
The pin will be in tension and the wood at the mating faces of the joint will be in compression.
Once that happens, the pin is pretty much out of the equation. For the usual stroke (other than a power break) the pin does not bear any of the impact force; the faces of the joint do.
"Feel" will be transferred from the shaft to the butt through the mating faces of the joint."
Edited for spelling.
