As the old saying goes... Locks only keep honest people out.
Thieves look for easy and quick scores. All a lock does is slow them down a bit.
Even a gun safe is fairly easy to break into using a cutoff wheel. Just cut through the side... not the door. Check it out on YouTube
This was a semi final match? Was there more then one referee? Maybe he was racking at the other table at the time? I could hear a break shot in the background just after this foul. Or am I the only one that caught this?
From this video, i cannot tell if the referee was even at the table on...
I find I play better, as in better cue ball control, when I use a lighter cue on a faster table, and a heavier one on a slower table. Other then that, not much difference on imparted spin.
It might just be me, but I like to try something for myself before I endorse or condemn something.
If something doesn't work for me, I try something else. Doesn't mean it won't work for someone else.
