I've been using an all-purpleheart 21 ounce break cue with a soaked-in-super-glue, 14mm leather tip, and I think I may have accidentally discovered a new type of Eight Ball break where you miss the apex ball by a mile and carom the cue ball around the table like a bumper car struck by lightning.
This leaves a nice cluster of balls in the middle that will frustrate most league players, and you'll often randomly make a ball by having the cue ball carom around so much.
The key is to just break from the rail as hard as you can with a ridiculously-overpowered break cue, and aim very carefully at any spot on the apex ball. If you screw it up and somehow hit what you're aiming for, the cue ball will still leap up into the air and startle your opponent, or perhaps even fly off the table and smite your enemies.
I can break more accurately with a house cue, but the Berzerker Break (TM) sets a tone of chaotic madness that makes men tremble at the possibility of a ball flying off the table and causing them to spill their drinks, and makes women swoon from all the possibilities of rounding off my sharp edges to improve me, if only they were given an opportunity to refer me to an optometrist and a therapist.
