Is this bias on actual reality...? I've owned a Z2 for decades that has the original ferrule and I've beaten on that cue with reckless abandon and experienced zero problems. I also currently play with a non-laminate LD shaft from Mezz that also has the shaft drilled out. No problems there either. Neither shaft I would call dead...Yes it's a low deflection shaft, but they have done it in a sensible way, so the shaft doesn't have the same issues as Predator Z/314 and OB shafts have where you hollow out the shafts so much and put on flimsy ferrules that tend to break or crack all the time. As a bonus you get a shaft with a better feel. Hollowed out shafts tend to feel more dead imo.
I understand my experiences may be the exception, but I'm rarely that lucky
